How to make the first submission of an iOS application for moderation?

Question

Apple Developer Program

You need to send the application for approval, everything is ready, except for analytics and push notifications.
Send it for the first moderation, so that later you can immediately send the modified version (moderation should be faster) and open it for everyone.
It is right?
The second question:
Is it necessary to immediately integrate push notifications in the first version, will there be any problems with approving the second version?

Answer 1

No, this is not correct. The next version will not be faster. They will not be related to each other at all.

Answer 2

1. Read off-line documentation
2. no, there should be no problems
