Custom role - Microsoft.DesktopVirtualization permissions not complete

When creating a custom role using Microsoft.DesktopVirtualization (with all permissions options selected) not all AzWVD CMDlets can be executed, when this role is assigned to a service principal. All CMDlets can be run without error when the service principal is contributor on the Azure sub. Errors when using the custom role are displayed below:

Disconnect-AzWvdUserSession Error

Send-AzWvdUserSessionMessage error

If access was recently granted, please refresh your credentials.

Both actions are not referenced in the custom role when looking at the JSON display, indicating they still need to be added before the Microsoft.DesktopVirtualization can be used for all CMDlets.
