url access to app

Hi community, I have an app, which have audiences and RLS, so in the workspace is not access to user/group. The setup is 3 audiences with 3 security groups with each rls in group  and three differents reports.

Audience A -> group A -> Report A

Audience B -> group B -> Report B

Audience C -> group C -> Report C

So the user A is inside group A

The user B is inside group B

and user C is inside group B

So the issue is the user "A" share the URL App via Share button -> Copy link.  The message "People with existing access to the app can use the link" to User "B"

The link is :  appIDXXXXXX &reportObjectIDXXXXXX & ReportSection XXXX & ShareLink&portalSessionIDXXXXX

The user B is tryting to access to URL and show him "we couldn't fine the report"

It resolved by short url : OpenAPPID&appIDXXXXX&experience=Power_bI whitout ReportSection.......etc

Two questions:

So whats mean   "reportObjectID", "ReportSection", and "SessionID"??

and if user D is inside group A could be access with "share URL" or should be the short_url?

The message "People with..." it's confusing to the users, so when the user should be use this "Share URL"?

Thanks in advance.
