Hello @dattasaurabh82. I am confirming your request.

Unlike submissions, this type of request is still handled manually. The Library Manager index maintainer occasionally comes through to clear all the outstanding requests. They will merge this pull request when it is done. You will get a notification from GitHub at that time.
