Another use case for this is that we often know the user who is clicking to initiate a chat, because they are logged into the website. With other chat systems (nudgespot, intercom etc) we could securely pass variables such as email address to link that up with the record in the portal - so we know who they are (which also allows proactive messaging if you go to the customer record and they are 'online' (e.g. have an active session on the website) - separate feedback about that!) FWIW we deploy the chat widget across our instances with GTM and it would be great to be able to add some parameters/tracking to push into analytics for example, when someone clicks to initiate, completes a chat, etc.
