The option "Restrict users to only share with users in their groups" makes the reader think that this option just applies to the sharing action. However this is not the case as all the applications should honor this setting and in some cases the impacted action is not sharing, but searching (contacts) or creating a conversation (Talk)

Adapt the description of this configuration to make the full scope of enabling it clearer to the reader

Additional context

Search the repository for the exact option text and inspect where its description is defined and displayed. Update the wording so it communicates that the restriction affects sharing, searching, and conversation creation; done means the revised description appears wherever this setting is shown.
