Purchasing Oto Templates + OTO Agency 20

Good evening, I bought the OTO templates 1000 and OTO Agency 20 but it does not appear in my account. Here are my proofs of purchases. Thanks for doing what's needed. To what extent can I give access to my clients? To give you an example I have a client to whom I created a website that wants to access my design and can modify them as it sees fit. How can I bill him? Do I give him access for a duration? For life? I do not see how I can sell because there is a collaboration on its site and also on the design? All these questions to stay in the legality. Do you have training videos?
