To enable inbox for the agents, inside the Customer Service admin center
Navigate to Agent Experience >> Workspaces >> Agent Experience profiles >> Manage
We can create new profiles or can add users to any of the existing profile that has inbox enabled
E.g. Customer Service Trial profile has the inbox enabled.
Below is the agent experience profile record, that doesn’t have inbox enabled.
Let us add one of the users to the below profile.
The Customer Service workspace before the user’s inbox is enabled. We can only see the Home tab.
