How to remove access to Goal Plans Section for Goals ?

Summary:

Hello our client has a specific requirement and we are encountering some issues.

They have goals specialist user roles and within those, not all user role who manages goals should have access to the Goal Plans section in the Goals menu.

I tried looking online but so far, little is disclose on the exact way or privilege to disable the "Goal Plans".

Thus i tried Page Composer but had little to no effect in disabling the section and similarly for privileges, no exact privileges that i saw allow explicitly access to the Goal Plans section.

I would be really grateful if anyone could give me some advices or direction on what to do to disable "Goal Plans" for some users only.
