I have a plugin that in TC8 registered project settings like this, but it seems like the page layout changed with the release of TC9, so the tab isn't visible anymore. I can't find anything in the online docs w.r.t. what the new page is, or a note on major version changes. Is it still possible to add a custom project settings tab for a plugin, and if so, how do I add it to a typical page (such as https://example.com/admin/editProject.html?projectId=My_Project)?
My plugin currently compiles and starts fine, and there are no runtime errors running on TC9.
