Take on Work with the Accept Case Button
Accept one or more cases at a time with the Accept Case button, now in Lightning Experience. Previously, this button was available only in Salesforce Classic on list views for cases that are assigned to a queue. Just like in Salesforce Classic, users in Lightning Experience see the button on the list view but they also see it on the record detail view for a case.
Where: This change applies to Lightning Experience in Essentials, Professional, Enterprise, Performance, Unlimited, and Developer editions.
