WIX App - How to disable Activity Feed for all booking staff member

Wix App - How to disable activity feed for all booking staff member

Background:
I have a number of collaborator in my Wix with “Booking Staff Member” which i believe is a lowest credentials.
They should only be able to view their own calendar and own customers in their Wix mobile app.

However, in this Wix mobile app they also have this section called “Acrivity Feed” which they can view all other activity that the website owner does, i.e. a customer fill up an online form, booking for other staff member etc.
They have the list view of all acitivty that is happening within the Wix app which is worrying for the owner.

The booking staff member should only view what work they have being booked on specific customers. Not including booking for other staff member.

Solution Needed:
How do i disable the “Activity Feed” for all “booking staff member” ? (The Red Part in the picture)

Note:
Red Square: Need to be disabled
Blue Square: OK to view as it’s individual staff booking.

Any advice is very much appreciated
