addPullRequestReviewComment has input AddPullRequestReviewCommentInput.
This has inReplyTo field.
But this input require pullRequestReviewId.
But when we want to create reply comment, this api respond error message “Review has already been submitted.”.
I think eather of pullReqquestReviewId or inReplyTo is required or be able to reply after submitted is correct specification.
REST API has a comment api. In this api it is
Or maybe addComment mutation should be able to reply comment.
Please consider this problem.
