Continuous Integration with GitHub

I need a opinion on the below usecase which is needed for CX POC.

Here is the use-case:

  • Development team works on continuous integration basis and trunk based development (only on main stream in Github)
  • On a single Feature development need, Development team does changes across multiple repository and need to trigger a review for the changed codes in a automated way.

How the same will be possible with Github ? is there a API or GitHub Actions already which is readily available to support such use-case ? Any hints?

Thank you!
