Did you intend to open this against flutter/website? I don't think the bot or the labels are set up for this repository yet. Perhaps we can adjust this issue to be for adding that?

Feel free to adjust as required. Godofredo can help add the required labels and bots.

@domesticmouse : There have been two PRs that cover autosubmit label and config changes: https://github.com/flutter/website/pull/9688 and https://github.com/flutter/website/pull/9216. Do either of these cover your concern? If not, can you clarify what else needs to be done?

I haven't been watching the PR queue on flutter/website. I'll close it for now and re-open next year if I see things not working as intended.

The autosubmit bot isn't set up for this repository yet, but I'd love to see it.
