hey guys i've been trying to get all the items for cool finishers and i finally got both kings belts but i been having a insanely hard time pulling them off doesn't help that i'm not very good at fighting games nor playing the  kings

i searched all over and tried the combos but they never do the finisher even if i K.O them with it King's F F F 2+4 he only grabs the person then flips them over on their back, while i can't even do AK grab it just does a pink glow effect whenever i try to grab someone mid air.

not using a fight stick either so any help on the D-pad would be great.
