Grab Reference links mentioned in PRs using github API

Hi Team,

Is there a way to grab the reference links mentioned in the Pull requests using Github API? In our scenario, we need to grab the list of all the PR links mentioned in a PR. I noticed Github adds a mention in the format “user mentioned this pull request” in the bottom of the PR with the links to the PR, however, I was not able to grab the referenced links from the API. I tried issues, comments and review_comments API and none of them had this information.

Could you please let me know if there is any other possibility to grab this information

Thanks !!
