Inside the CRM form, you can configure tabs. If you don't use business processes, automation rules, or Zoom, remove these items from the menu.
You can set up tabs in the form as well as in the timeline.
To customize tabs, click More > Configure Menu.
You can swap or hide unnecessary items. To do this, just drag them to another place or click on an item and press Hide.
In this case tabs are not deleted, but moved to the More menu. At any time you can return them to the default form view. Click Reset Menu.
The timeline items are set up in the same way.
