Check out finetuned GitHub permissions

When a PR passes review, such as here, assigning the user fails:

Traceback (most recent call last):

The error says the bot needs Admin permissions. But perhaps there is a way to finetune it just for assigning people to PRs. Check out the GitHub docs; Triage role should be enough for "Close, reopen, and assign all issues and pull requests".
