How to reduce the number of steps when requesting permissions from a user via fb.login?

Question

Facebook

Good afternoon.

At the moment, if a user uses fb.login on my project, then a window opens where he passes authorization in fb and then selects a facebook group in a few steps, gives the go-ahead for rights, selects a facebook page. At the same time, at each step, he must manually pierce everything.

At the same time, for a number of systems, the login looks and the request for rights looks like one screen (where all rights at once, all groups and pages are marked with a checkmark).


I looked at the Facebook api on fb.login and did not understand why they have such a convenient connection, and my user is driven through several screens.

Can you suggest a reason?
