Get-MgBookingBusiness Returns Zero Results

[YuriySamorodov]

Describe the bug Both Get-MgBookingBusiness and Get-MgBetaBookingBusiness return no results even with -All parameter used

To Reproduce Steps to reproduce the behavior:

1. Open PowerShell 5.x or PowerShell 7.x (not PowerShell ISE) under Global Admin account
2. Connect to MS Graph with Connect-MgGraph
3. Connect to Exchange Online with Connect-ExchangeOnline
4. Execute $mgbookings = Get-MgBookingBusiness -All
5. Run $exobookings = Get-Mailbox -RecipientTypeDetails SchedulingMailbox
6. Compare $mgbookings.count and $exobookings.count

Expected behavior Get-MgBookingBusiness should return a lot of items
