After you’ve assigned the “Sales Console User” permission set license to users, you need to create the Sales Console permission set that users need to access the sales console.
|Available in: Salesforce Classic|
|Available in: Professional, Enterprise, Performance, Unlimited, and Developer Editions|
|To create permission sets:||“Manage Users"|
From Setup, enter Permission Sets in the Quick Find box, then select Permission Sets.
Create a permission set. When creating the permission set, select the user license type None. If another license type is selected, you won’t be able to add the Sales Console user permission to this permission set.
On the Permission Set page, click App Permissions.
Select the Sales Console permission and click Save.
Assign this permission set to users. Do this from the Permission Set License Assignment section of the user’s detail page.
