Explanation
Verifying that users are assigned the Chat feature license is the configuration option that should be verified if agents cannot see the Chat footer component in the Service Console. A Chat feature license is a type of license that enables users to access Chat functionality, such as initiating, receiving, transferring, or ending chat sessions, sending quick texts or files, or viewing chat reports. Users must have a Chat feature license assigned to their user record in order to use Chat in the Service Console.
