Can't get actions run on forked repo

I have forked https://github.com/fundamental/rtosc to https://github.com/JohannesLorenz/rtosc, but the actions from the original repo do not seem to run on my fork.

The original repo has a green checkmark on the newest commit, mine has none. My actions tab looks like a startup guide, rather than listing build jobs. I even deleted my fork and forked again just now, but no change.

Can anyone please help? Thanks on advance.

Edit: The reason I ask is because I want to push branches on my own fork and see if they pass the CI before pushing to the original repo.

Sorry, I just see that this repo just does not have any Github Actions on master. This can be closed.
