Application Studio newbie question

This should be fairly simple, I’m sure I am missing the obvious. But I want to add a tab at the top of jobs next to Assemblies.

I’ve added it as a page on the application map, the way it shows on the map I would think it would appear like I want it to.

No matter what I change the Page type too I can’t get it to appear where I want.

Just for context the new page I am trying to add has all custom fields on it.
