Error integration with Teams "Access Forbidden to use Vilt Provider features"

Summary: Error integration with Teams "Access Forbidden to use Vilt Provider features"

Content (please ensure you mask any confidential information): Hi to all,

after we made the integration with Teams successfully we created a virtual account with an instructor, and also this step was successful.

After that we created an activity with a "named virtual classroom" (it was successful too) but when we log in with the employee we are not able to see the URL link.

Furthermore we noticed that in the section "Configure external providers" if we enter in Microsoft Teams and click on "view errors" we see the error: "Access Forbidden to use Vilt Provider features" (see the picture below).
