totem not working

im trying to make a custom totem of undying that triggers upon death. i have tried the method with the global event ''entity dies' and then cancelling it. the problem with that method is the fact that all of my items drop and i get the 'you died' screen despite still being alive. i would like to know if there is a way to trigger it when the player dies instead of checking for the player's hp cause then it doesnt trigger if you get one shot. any help is appreciated.
