By default, the extended profile page is disabled. You can enable the extended profile page, so after clicking on a contact, an employee will no longer go directly to the chat, but to the employees profile page (the chat will of course remain and can be accessed separately).
In the administration area, go to Settings and click on Users.
Click on the pencil icon next to Enable extended profile page and activate the setting.
It may take a few minutes for the setting to take effect.
As an employee, switch to Contacts and click on an employee's name.
Now you will see the extended profile page activated in step 1.
