Searching for help, Trigger that activates for 3 Seconds after a specific buff is lost on the player

[late atlas]

Title says it, im trying to create a trigger that would only trigger right after a specific buff on the player is lost/ends for just a few seconds afterwards. I might just be stupid or blind, but i simply cant find a solution. Thanks in advance

you can use a combat log trigger for that.
combat log - spell aura removed - source unit: player - spell id or name - timed 3 secs
