Free accounts to test rcvideo in prod are not working?

I’m trying to test rcvideo in prod but it seems my regular account does not have access to rcvideo:

Sorry, you currently don't have permission to access this service. Contact your administrator to change permissions.

And free accounts are not constantly disabled:

Sorry, access to this account is disabled. Please contact your company admin. If you're the company admin, call support at +1 (888) 8984591.

How can I enable an account for testing?
