Add Customer Portal

Hi,

I have to create Customer Portal for External (Portal) users. I have created an external user & 3 Portal-Pages for 3 different clients. 

I followed for creating Portal: Portal | Creatio Academy | Improve your skills with Creatio Training Courses & Certification

Query:

(Portal Application)

1. In workplace, only 'self-service' is there. How can I show 'Customer-Portal' also?

2. Based on External User's role or designation, only single Main-Page must be visible there.

i.e. For Employee of Client 'A' -> Portal Main Page 

      For Employee of Client 'B' -> Case Analytics

      For Employee of Client 'C' -> Demo


Platform: Creatio:Energy (Freedom UI)
