I am testing that from a forked repo I cannot auto-merge a PR, the response I get is:

2020-11-10T19:46:56.465Z INFO Event name: pull_request

2020-11-10T19:47:07.482Z INFO Current PR status: mergeable_state: blocked

Not sure if I get blocked because the GITHUB_TOKEN is read only on forks or if is something else, just want to make sure that PRs coming from forks cannot get merged.

Any assistance will be appreciated.
