Cannot publish action to marketplace on forked repo

I forked code from GitHub - mattallty/jest-github-action: Jest action adding checks with annotations to your pull requests and coverage table as comments and add some extended function in this repo.
But I can’t find a way to publish my action to marketplace, I have an action.yml in my repo root directory, but there isn’t option to publish this action to marketplace.

I tried to create a new repo by javascript-action template and there is a button for me to publish it into marketplace.
