Multiple SSH keys not working on GitHub Enterprise

[lcmgh]

Hi!

I followed the docs to setup multiple ssh keys by generating them with comment parameter -C and adding the git URL from my GitHub Enterprise repo.

https://private-github.myenterprise/org/repo.git

I ensured correct keys were set as secret and deploy key but it seems correct keys are not mapped.

    - uses: webfactory/[email protected]
      with:
          ssh-private-key:  |
            ${{ secrets.DEPENDENCY_ACCESS_2 }}
            ${{ secrets.DEPENDENCY_ACCESS_2 }}

ERROR: Permission to abc denied to deploy key fatal: Could not read from remote repository.

Might it be because only github.com URLs are supported? https://github.com/webfactory/ssh-agent/blob/dc622c59e471395a5b1e0d96279fe835c87a218b/index.js#L67

Thanks
