Review of a GitHub pull request without any reviewers

My previous LLVM contributions have been to clang-tidy and llvmbot automatically added appropriate reviewers. I created [OpenEmbedded] Fix include and lib paths for multilib targets by mikecrowe · Pull Request #121302 · llvm/llvm-project · GitHub nearly a month ago and whilst llvmbot added some labels, it did not add any reviewers. The change is similar to a previous one, so I could add the author of that change but I don’t have permission to add reviewers to the pull request myself.

What is the correct process for encouraging review of a change without reviewers assigned for those of us that lack commit access? All the advice I could find suggested adding a “ping” comment, but I’m suspicious that no-one would see such a comment if I did so.

All advice gratefully received.

You can cc potential reviewers by posting a comment with @reviewer-name in the body. Typically these would be folks who modified this part of the codebase most recently and those who reviewed those PRs.

Thanks. I had tried to cc the author of the previous change but that was in the Phabricator times and I couldn’t find a matching GitHub user name. I did find a GitHub username that seemed to match the reviewer of the previous change, but since you’ve already added three reviewers I’ll see if they respond first. Thank you for doing that.
