How to add a secondary project page options?


I’m working on a Jira Cloud app and I’m using Forge with Custom UI.
I’ve created a project page module and now I can access it from the left-hand side menu.
My question is, is it possible that when I click on this tab from the left-hand side menu, another menu will open?

I have several sub-modules that I want to add under this main project page option.

Here’s an example:


I don’t think it is currently possible to create an expandable menu item. You’ll have to present the options on the project page that is opened by the menu.
