Auto-comment when a PR touches unowned code paths

[chai-unitary]

I want to use Auto-comment Github action but I want to trigger it based on a unique use-case

Unique because it doesn't seem to be available off-the-shelf: https://github.com/marketplace/actions/auto-comment

I am using CODEOWNERS.md to define which code paths are owned by which teams within our org.

I now want to configure a GH action that would comment something like

Alert/Warning ⚠️: You're touching <team A>'s codebase. Have you confirmed this change with them? Do they have knowledge of this?

Is it possible to tie in codeowners with auto-comment. If yes, can you recommend how? Thanks

Expected Behavior

Trigger auto-comment based on PR touching files in codeowners [created by author outside the owning team]

Possible Solution

Not sure
