Understanding the Review Life Cycle: Submissions for New Listings or Updates?

I have recently published my first every activity on marketplace , its in review right now

i have gone through the docs for marketplace , it was detailed explained about the process of dos and donts about how to submit a listing , but there is barely any informationed after the listing is submited by the author/owner , i have this points that needs to be cleeared so i can contnue to develop and maintain furthur listing , the points are as follows

1 :- How the review lifecycle works , this include a new listing or an update

2:- How long a review typically takes (probably got a answer here )

3:- How detailed are the feedback by the marketplace team if there is a change or update needed from the author/owner, does the feedback is also sent to the registed mail id or on the marketplace profile only, and does level of details in the feedback depends if the author/owner is a organization or an individual

4:- What are the different status messages for listings? Currently, mine shows ‘InReview.’

I hope the team can provide a detailed explanation for these concerns. Thanks!
