I figured out there are plenty of issues, and you are using the GitHub stale action to help you in that way.
I was a considerable contributor to it, and now I made another stale action, with more features (by using the GraphQL API) and from scratch.
You may take a look at the possible options based on how you are currently helping yourself with the triage to make it even less time-consuming.
Kindly let me know if you have any questions/feature requests, and congratulations on the time and efforts put on this framework 🚀
