WeakAura triggering unit in action

[Cracked]

Hello, I have a debuff weak aura, which I would like to autoclone in a dynamic group. However, for this I don't think I can use a custom trigger, and I need to save the name of the player who got the debuff. Is it possible to get the triggering unit in the on show action via some internal variable?

Did you try %n?

If you don't want to do anything else with the name, you can just use %n and it'll display the person that has the aura.
If you need it in %c to do anything else with it:

function(...)
local name = select(5, ...)
end

the 5th argument of the varargs should contain the name you want
