The safest method to find a trigger is to 1st log the trigger using event logger and rerunning it.
Some AntiCheats, such as Reaper have some type of verification. (normally a token).
2.1 Bypassing a token can be done by logging the event once and rerunning it. (It can work on some less configurated servers)
2.2 If you want to be safe while bypassing a token, Nexus (premium menu) has safes events that bypass this type of protections.
