New-MgSecurityAttackSimulation - endUserNotificationSetting properties seem to be broken

Describe the bug

Trying to create a new attack simulation with New-MgSecurityAttackSimulation, but once I introduce settings for endUserNotificationSetting, the cmdlet always errors with:

• `{"Code":400,"Message":"Bad request","Target":null,"Details":[{"Code":400,"Message":"Parameter endUserNotificationId is not valid","Target":null,"Details":null,"InnerError":null}],"InnerError":null}

Status: 400 (BadRequest)
ErrorCode: UnknownError`

If I set endUserNotificationSetting -> settingType = unknown, it ignores that property and everything under it, and the simulation creates OK. The issue seems to be no matter how I try to include notification settings, creation via Graph results in an error. Even using the documented creation from the MS KB does not work:

• https://learn.microsoft.com/en-us/graph/api/attacksimulationroot-post-simulation?view=graph-rest-1.0&tabs=powershell

Expected behavior

Expect to be able to provide notification options to API/cmdlet, and have them work.

How to reproduce

Purged tenant data, apologies if I messed up formatting, but this should be a mostly complete example that will not work as is (unless changing endUserNotificationSetting = @{ settingtype = "unknown"}

[Microsoft.Graph.PowerShell.Models.IMicrosoftGraphSimulation]$newCampaignData = @{
#AND/OR just $newCampaignData = @{
    
    AttackTechnique = "credentialHarvesting"
    AttackType = "social"

    "payload@odata.bind" = "https://graph.microsoft.com/v1.0/security/attacksimulation/payloads/$($payloadID)"
    "landingPage@odata.bind" = "https://graph.microsoft.com/v1.0/security/attacksimulation/landingPages/$($landingPageID)"
    "loginPage@odata.bind" = "https://graph.microsoft.com/v1.0/security/attacksimulation/loginPages/$($loginPageID)"

    includedAccountTarget = @{
        "@odata.type" = "#microsoft.graph.addressBookAccountTargetContent"
        type = "addressBook"
        accountTargetEmails = $aryTargetUsers
    }

    TrainingSetting = @{
        # Even when this is set to "noTraining", fails.
        settingType = "microsoftManaged"
        trainingCompletionDuration = "fortnite"
    }

    endUserNotificationSetting  = @{
        notificationPreference = "microsoft"
        settingType = "noTraining" #I have tried every supported value for this - setting to unknown lets this work, anything with training in name fails.

        positiveReinforcement = @{
            # I've tried every combination I can figure out for enduserNotification data, but no matter what I

            # "endUserNotification@odata.bind" = "https://graph.microsoft.com/v1.0/security/attacksimulation/endUserNotifications/$($positiveNotificationID)"
            # endUserNotification = "https://graph.microsoft.com/v1.0/security/attacksimulation/endUserNotifications/$($positiveNotificationID)"
            # endUserNotification = ($allEndUserNotifications | where NotificationType -eq "positiveReinforcement") #This is a GET for the correct notification, containing all properties
            deliveryPreference = "deliverImmedietly"
            defaultLanguage = "en"
        }

        simulationNotification = @{
            targettedUserType = "compromised"
            "endUserNotification@odata.bind" = "https://graph.microsoft.com/v1.0/security/attacksimulation/endUserNotifications/$($simulationNotificationID)"
            defaultLanguage = "en"
        }
    }

    createdBy = @{ email = "email@email.com" }
    launchDateTime = (Get-Date)
    payloadDeliveryPlatform = "email"
    Description = $newCampaignName
    DisplayName = $newCampaignName
    DurationInDays = 2
    status = "draft"
}

No response

Known Workarounds

Per above, tweaking this will make it work, but it ignores all notification options.

    endUserNotificationSetting  = @{
        notificationPreference = "microsoft"
        settingType = "unknown"
    }
