At 5 PM, when business hours officially end, an automatic out-of-office
message is sent to customers. However, this creates a poor experience if
an agent is actively chatting with the customer. This update ensures
that the out-of-office message is only sent if no agent message has been
sent in the last 5 minutes. If the customer reaches out again after 5
minutes, the out-of-office message will be triggered.
