As far as I know, it’s not possible to locally show the trigger being disabled - meaning, that visually it will be the same for every person in the server. I might be wrong though.
What you can do, is add the players to a map when they trigger the device. If they then again try to trigger the device, you check the map for their name. If it exists, they’ve already triggered the device, so therefore we just ignore the trigger. Otherwise, we can pursue as we would normally.
Hope that makes sense.
