Where is this configured?
Go to the Users section.
Select a user with the Representative role.
You'll see an option to define contact visibility:
All contacts: the user will see all contacts in the account.
Only assigned contacts: the user will only see the contacts assigned to them.
What happens when “Only assigned contacts” is enabled?
In the Contacts tab, the user will only be able to view and access leads or clients assigned to them.
When viewing the full history, it will also be filtered to show only the contacts assigned to that user.
This is useful if you want to limit access for certain profiles and maintain privacy or order within the sales team.
⚠️ This feature only applies to users with the "Representative" role.
Example of use
If you update your own user with this option enabled and refresh the session, you'll see that:
You will no longer have access to all contacts.
You’ll only be able to access those specifically assigned to your user.
