Trouble retrieving comments provided for "Request Changes" and "Review Required"

I am able to get review comments and comments provided from Github API. But I did not find any API to retrieving comments provided for “Request Changes” and “Review Required”

:wave: @aparnan, hello there and welcome to the GitHub Support Community!

If someone has created a review that requests changes and you’d like to retrieve that reviews comments, you could:

If a review is required, this indicates that the base branch of the pull request is a protected branch that requires at least one or more approved reviews before any changes can be merged in. Our Branches API is extensive and there are a number of endpoints for querying, modifying, or deleting branch protections. I hope this context helps!
