Currently, all time-based triggers are available for Chat, but not for Messaging. This is probably related to the fact that both are different technologies. However, from a user perspective, the web widget looks pretty much like a chat client, and therefore there is an expectation of a real-time chat workflow with messaging.
One specific use case that we would like to implement after a handover to a human agent:
When a user waits more than 5 minutes without a response from a human agent, we want to send an automatic message to the user, e.g. that we have a created a ticket for the request and that we follow up at a later time.
We did not really find a good workaround for this, e.g. making this message dependent on the size of the waiting queue is not the same. With time-based triggers we could achieve a much better communication with the customer in case of longer waiting times.
