Would somebody be able to advise the best way to go about this from a supertokens perspective. Essentially I want: - a user to be able to sign up to an app and use the platform (Simple, and implemented). - a user can also create user-generated content for sale inside the app - a user can be subscribed to the main platform as well as many UGC subscriptions I know this will take some work from a payments perspective, but strictly from supertokens management, I am not sure of the best way to go about this. Thanks
