Automating Client Connections to Make Scenario

I am reaching out because, as a company, we have developed an automatic video generation system .
We now have a growing number of clients, and up until now, we have been manually connecting our clients to the YouTube, Facebook Pages, Instagram for Business, and other modules. We connected our clients to our Make account, which allowed them to create a connection.

However, with the increasing number of clients, this method is no longer manageable for us.

Is there a way to connect all these clients through OAuth2, for example? We could send a link to our clients, allowing them to authorize Make to interact with their YouTube account, and then we could retrieve the necessary tokens from our account to integrate the client into our workflow.
