Currently when trigger value turns to OK after being PROBLEM we can send Recovery message.
It is not possible to execute remote commands on trigger recovery.
There is a workaround to use condition Trigger value = OK in another action and execute commands in operations there but that leads to another problem described in
ZBX-8220 - action for OK state is unnecessarily executed when host returns from maintenance with data collection and trigger was in PROBLEM state during maintenance. That is not desired behavior in this case.
