PowerShell Creating WVD The user isn't authorized to query the management service


For a vert long time we are using Windows server remote desktop services. My boss seems interested in Microsoft Azure Windows Virtual Desktop services so, I have been asked to test and created a demo environment so that he can test the feasibility as he was praising about it.

So, I started to create a test environment but getting the below error not sure how to get passed it since I am new to Microsoft Azure

I am leaving the below screenshot hoping that it could help someone to point me in the right directions
