Noob needs help with RDP Services

I am new to Windows server management.  I setup a 2019 Server in a VM (Hyper-V).  I installed the licenses we got for RDP from MS after installing the Remote Desktop Services.  I am getting an error about Remote Desktop Licensing Mode is not configured.  Tells me to use Server Manger to specify RD Connection Broker.  Either I neglected to install it or configure it, not sure.

Articles I find say go to Server Manager -> Remote Desktop Services -> Overview...  BUT, that tells me I am logged in with a local account but must use a domain account to manage servers and collections.  Again, not using a DC.

This server is not part of a domain.  We do not run AD internally only AzureAD online.  We have 1 program we still run internally and users RDP to it. 

Should I remove the service and reinstall?  What about the licenses I added already?  How to I keep them?

Any assistance will be greatly appreciated...
