Hello Ahmad,
Not sure what do you mean 'provide Appointment in ic webui'. Do you mean you want to search, display or create activity in IC webUI?
From my understanding, these activities you are talking, are the same activities as in non-IC roles? For example, in business role 'salespro', there is a menu 'activities'. You are not talking about 'interaction record', right?
If my understanding is correct, you can add work center id to the IC business role. For example, work center id of 'Activities' for salespro is 'SLS-ACT', you can add this 'SLS-ACT' to the navigation bar profile which is assigned to your IC business role.
It is the same for 'Canlenar', the workcenter id is 'CT-CALENDR'.
Best Regards, Corrine
