Unable to hide Framework App from Menu

Hi,

I am trying to create a custom user landing page using frappe custom modules and workspaces. I could achieve creating custom pages and workspaces but on top left my dummy user ( with limited access ) still see “Framework” as app. I want user to only see “Test App” and its workspace.
When I restrict all access outside my custom module, I get page not found error on user login. So I had to provide either access to “core” module OR “workspace manager” to again make user access the frappe ( which comes with “Framework” of course. I am not expert on this, can somebody help ?
