Andrewds1021 I don't think you can even do that before it is enabled. Enabling custom JS is separate from Wikia approving individual edits to your JS through the review process.

Yeah, for wikis doesn't have JS enabled, then creating .js is not possible. For wikis that have JavaScript enabled, they could test the side-wide JavaScript without submitting their review (to see the changes for themselves), but Fandom Staff can't review it if the admin didn't click "SUBMIT FOR REVIEW" button. And the JavaScript (or the revision, I should say) must be approved in order to work site-wide.

If the admin wants the JS to be enabled in their wiki, then they contact Staff via Special:Contact. Yes, you're right, enabling custom JS is separate from Wikia approving individual edits to your JS through the review process. Approving JavaScript is after the user clicked "SUBMIT FOR REVIEW" button after they've publish their JS edit and enabling JavaScript in a wiki is by contact Staff via Special:Contact.
