Configure LCS connectivity for the tenant

Hello everyone,

I am working for Dynamics 365 Finance And Operations On-Premises installation.

now I have a question about step 11

https://docs.microsoft.com/en-us/dynamics365/unified-operations/dev-itpro/deployment/setup-deploy-on-premises-pu12#configurelcs

I have a azure active directory id but i have not a azure subscriptions.

I can run this comment  .\Add-CertToServicePrincipal.ps1 -CertificateThumbprint <OnPremLocalAgent Certificate Thumbprint>

and I see login page for AAD. I'm trying to login, id is seen and the subscriptions gives error.

I am using VHD on local

do I need this any subscription? 

If you have, which subscription should be received?

Can you write a detail about this step?

Thank you.
