Describe your question

I came across a situation while using this action where while publishing results to external repository I was getting below error:

/usr/bin/git push origin gh-pages
remote: Write access to repository not granted.
fatal: unable to access 'https://github.com/username/repository.git/': The requested URL returned error: 403
Error: Action failed with "The process '/usr/bin/git' failed with exit code 128"

I have gone through action's README for this known issue, still I spent quite some time figuring out what I was doing wrong.
eventually I found out that the token I was using to checkout repository (which will be published with this action) was gh app generated token and I was using my PAT in action to publish to gh pages, so I had to change the checkout action to use my PAT instead and then actions was able to publish.

so while publishing to external repository, checkout and publish both needs to use PAT only it seems, not sure if this is again a known thing but this should be mentioned in that known issue section.

my question is that whether such gh app based token can be used for this action? because we're prohibited from using PATs anymore in our CI workflows.
