Can’t check “Run workflows from fork pull requests” in organization settings

Hi folks,
here at ITS Angelo Rizzoli (ITS Rizzoli · GitHub) we’re teaching GitHub to our students in the Software Architect course.

For us is very useful that students PR receive our org tokens because we’are using GitHub Actions to add/remove labels to PR automatically after checking homework assignments :slight_smile:

We’re trying to enable the feature from here Sign in to GitHub · GitHub but seems unavailable as follow

How can we enable it?

Regards,
