Pagination

Please, can you give some hints on how pagination works with Flask.
Using the list method, for instance docs_list = mendeley_session.groups.get('3b7a5bd7-ba7a-36de-a961-f88d113ba523').documents.list(page_size=5), I'm not able in figuring out how to manage the object Page to navigate through the other pages

thank you,
francesco
