Get-MgBetaIdentityConditionalAccessPolicy does not return ExcludeGuestsOrExternalUsers "members"

Describe the bug

I want to create a conditional access policy that excludes a specific service provider, to generate the required JSON body I created the policy in the user interface and fetched the policy via Get-MgBetaIdentityConditionalAccessPolicy. However, the Microsoft.Graph.Beta.PowerShell.Models.MicrosoftGraphConditionalAccessPolicy does not contain the "members" property and values. I was able to find the body I need by using the -debug parameter. I suspect this issue affects include and exclude for more than just serviceproviders but have not confirmed that.

"excludeGuestsOrExternalUsers": {
        "guestOrExternalUserTypes": "serviceProvider",
        "externalTenants": {
          "@odata.type": "#microsoft.graph.conditionalAccessEnumeratedExternalTenants",
          "membershipKind": "enumerated",
          "members": [
            "xxxxxxxxx-xxxx-xxxx-xxxxx-xxxxxxxxxxxxx"
          ]
        }
      }

Expected behavior

The Microsoft.Graph.Beta.PowerShell.Models.MicrosoftGraphConditionalAccessPolicy object should contain the excluded members.

How to reproduce

1. Using the entra ID portal, create a conditional access policy with an excluded service provider
2. Run the command $p = Get-MgBetaIdentityConditionalAccessPolicy -id
3. Look for the tenantID that was excluded and you will see that it is not present. It should be at:
   $p.conditions.users.ExcludeGuestsOrExternalUsers

### Other information
No other information

Start by reproducing the issue with Get-MgBetaIdentityConditionalAccessPolicy on a policy excluding a service provider, then inspect $p.conditions.users.ExcludeGuestsOrExternalUsers and compare it with the debug JSON. The work is done when the MicrosoftGraphConditionalAccessPolicy object exposes the excluded external-tenant members and the returned value matches the policy response.
