permission Schedule appointments in a resource room

hello,
I want only one user to be able to schedule resource room meetings and the other users get rejected. Do you know how?

I know this command : 

Set-CalendarProcessing -Identity "test-zoom-room10@test.il" -AutomateProcessing AutoAccept -BookInPolicy "JAMtestuser" -AllBookInPolicy $false

But even if I use this command - other users can make appointments
