Hi there,
When adding a new monorepo to the monorepo.json, please note that:

• Any dependency update(s) from this monorepo will be upgraded in a single PR
• If the dependencies are not all versioned identically (i.e. they're all at 16.0.5 and a release in one requires all being updated) this will lead to Immortal PRs
  • This is not be the intended behaviour, and is generally not recommended by Renovate maintainers. We only accept it if the packages strictly need to be updated together.

It is worth both the author of the PR and the reviewer confirming that this is the intended behaviour.

we usually don't accept mono repos if they don't share the version because the PR get's immortal (not ignorable).

we only allow it if they strict must be upgraded together.

I think this fits that criteria? chat and all the @chat-adapter/ packages are all getting published to the same version

please add that clarification to the PR body. it will make review much easier.
