What setting do I use on a eos 80d to fire a remote or attached hotshoe stroboscopic flash set at 10 x 5hz

I bought a Godox TT600 for my canon eos 80d and yes for normal flash on or off hot shoe it works as expected however I can not get the multi flash to trigger ( or any other setting) out side of A+ ( automatic ) on the camera. What am I doing wrong.
