NPS Extension for azure MFA and multiple tenants?

Hi, is it possible to setup one NPS server with the Extension for Azure MFA to authenticate against multiple tenants? The onprem AD has azure ad connector for each domain and the users are in sync with there tenants. Its a RDS setup with one RD Gateway and one NPS server and multiple RD servers. I need email address removed for privacy reasons and email address removed for privacy reasons etc. to authenticate with MFA, but i can only get the users on the tenant thats linked in the NPS Extension for Azure MFA to work. I dont think its possible to setup more than one tenant in one NPS server (Extension for azure MFA). I get this error in the NPS log

NPS Extension for Azure MFA: CID:xxxxxxxxxxxxxxx : Access Rejected for user email address removed for privacy reasons with Azure MFA response: AccessDenied and message: Caller tenant:'xxxxxxxxxxxxxxxxxxxxxxx' does not have access permissions to do authentication for the user in tenant:'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx',,,xxxxxxxxxxxxxxxxxxxxxx

The ID in the Caller tenant and the user tenant in the error is correct, so something have to work? I cat find a way to allow the Caller tenant to access users in the user tenant.
