[Bug] Revoke SignInSessions not working

Describe the bug

Followed the guide - https://learn.microsoft.com/en-us/graph/api/user-revokesigninsessions?view=graph-rest-beta&tabs=csharp

var graphClient = InitiateGraphClient();
await graphClient.Users[azure_user_id].RevokeSignInSessions.PostAsRevokeSignInSessionsPostResponseAsync();

Output:

{
    "additionalData": {
        "@odata.context": "https://graph.microsoft.com/beta/$metadata#Edm.Boolean"
    },
    "backingStore": {
        "returnOnlyChangedValues": false,
        "initializationCompleted": true
    },
    "value": true
}

Even after 10 mins I am able to utilize refresh_token and generate new access_token

Microsoft.

Expected behavior

Should have revoked access_token and refresh_tokens

How to reproduce

var graphClient = InitiateGraphClient();
await graphClient.Users[azure_user_id].RevokeSignInSessions.PostAsRevokeSignInSessionsPostResponseAsync();

### Configuration

- OS: Windows 11
- Microsoft.Graph.Beta - 5.93.0-preview

### Other information

_No response_

Start with the documented RevokeSignInSessions call in the issue and reproduce it using Microsoft.Graph.Beta 5.93.0-preview on Windows 11. Verify the returned value and whether an existing refresh_token can still generate an access_token after ten minutes; done means the observed behavior is explained or the SDK/API issue is isolated.
