has anyone had any luck setting up the Pulumi GitHub App lately? I can't seem to get it to comment on a PR at all. I've been experimenting with both Google Cloud Build and GitHub actions to run

pulumi preview

and/or

pulumi up

as per the tutorials, and I've enabled the app for all repos in my organization, but it refuses to fire at all. Are there some undocumented naming convention rules about org/project/stack/repo naming that I'm missing?

Commenting is working for me as per the tutorials (enabled for all my repositories).

For me the bot comment was added on my very first PR but never saw a commant on subsequent PRs again.
