Authorizing User to Specific Pages

More than likely this has a simple answer but I’m new to the application development environment and Auth0 environment. I am looking to build a dynamic app (Frontend in ReactNative, Backend in SpringBoot) so when a user s in they have access to pages they have “created” in a sense. Is there a way I can dynamically make it possible for users to be able to view pages they “created” and not ones from other users? Is this possible with Auth0 and if so how would you go about it? Thanks in advance!
