With the buttons “Accept” and “Decline” you can indicate in the chat to other end users whether you are going to take action on an event (Accept) or if you are not able to take action (Decline).

This way end users know among themselves who will and will not see what is going on. Incidentally, if no one (no end user) accepts the event received, a push message will be received a little later indicating that no one has responded (In chat: No response to alarm / in Events: Chat timeout).
