livelink subject activation

is there a way to know if the live link subject activates like the yellow turns to green ? , I was trying to make a trigger with a blueprint to execute an action when such an event occurs , but I didn’t see a way to know if the subject was active , the only one I saw was to check if the subject is enabled , which returns true if there is a live link subject in the source. Is there a way to find the active state of a subject?
