@iamsumit would you be able to update the tests to use the new GitHub output? the tests seem to be failing.

I fixed the tests. However, the integration_installation and integration_installation_repo events were failing due to the same issue. There is no such events listed on the github docs.

Running into this same issue. I was able to replace the dependency with your fork, but wondering what the approval process is to get this merged in?
