pull request closing references

I wonder whether there is a supported way to parse/retrieve references to issues/pull requests from pull request body descriptions like github.com supports using e.g. `closes #123`

all official keywords are described on https://docs.github.com/en/get-started/writing-on-github/working-with-advanced-formatting/using-keywords-in-issues-and-pull-requests

I would love to either parse the pr body description or call a api endpoint to get a list of referenced issues from a given PR

No repository file or test is named. Start by reviewing the linked GitHub documentation and the existing pull-request API methods to determine whether referenced issues are available from an endpoint or must be parsed from the body. Done means the supported approach is defined, implemented in the client, and covered by tests.
