how send whisper

[Lkledu]

Hi, i'm doing my first addon and i want to put a button to send a whisper for the player's target. But i'm having problem to set the inputChat to whisper

i'm using:

mission.SetChatInputText(userMods.ToWString("/whisper " .. name), string.len("/whisper ")+string.len(name))

i tried a lot of different SetChatInput functions like SetChatInputType and SetChatInputArgs but neither one works (SetChatInputType works when i pass "party" or "guild" but not "whisper").
