Setting up App-level Impersonation on MS 365 for a zoom room using PowerShell

[Stackable1]

Hi, I'm trying to follow this guidance from zZoom to setup a Zoom room on MS 365

Setting up Zoom Rooms with Office 365 – Zoom Support

I get to step 5 under App-level Impersonation and the PowerShell command provided makes no sense at all to me.   I have tried at least 20 different variations and get nothing but syntax errors.  

New-ManagementScope -Name "ResourceMailboxes" -RecipientRestrictionFilter {RecipientTypeDetails -eq "RoomMailbox" -or RecipientTypeDetails -eq "EquipmentMailbox" -or UserPrincipalName -eq 'DedicatedUser'}
Note: Replace the text DedicatedUser with the User Principal Name of the Dedicated Service Account User (this usually matches the Dedicated Service Account User's email address).

Does anyone know how to formulate this syntax correctly? 

I have a service account like this for example.   ***********  and a Resource Room in Exchange for example of ***********   I have no idea how to make this command work. 

Thanks

@Stackable1 sorry for the late reply.  Could you perhaps post a screenshot of the error message?
