How to setup Claude Code for Github Enterprise Cloud ?

 I am trying to configure Claude Code to run on Github as a Code Review agent

I would like to install the marketplace app https://github.com/apps/claude , but we are using GHE github enterprise cloud for our organization and the standard instructions dont
work. Our DevOps tried following the manual setup instructions https://github.com/anthropics/claude-code-action/blob/main/docs/setup.md but that didnt work.

I see that there some closed related issues:
- https://github.com/anthropics/claude-code-action/issues/40 setup on GHE
- https://github.com/anthropics/claude-code-action/issues/520 git authentication on GitHub Entreprise
but they lack clear working instructions. one of them references https://github.com/anthropics/claude-code-action/blob/main/examples/claude-auto-review.yml but this file does not exist.

Please provide guidance on how to set this up on GHE cloud !
