Messaging: Allow agents to request satisfaction ratings

Before messaging, agents had the ability to request CSAT ratings and it was a more personalized experience. Since we've turned on messaging for out web widget (about 3 weeks), we have seen negative impacts in our numbers. Our overall satisfaction rating has dipped about 2%. We've had about the same number of negative ratings as usual, but we have 80 less positive ratings. I would like the ability for agents to request satisfaction ratings like they could with chat or at least a more personalized/customizable experience so we can get our numbers back up!
