Ultra instinct kamehameha (Dragon ball xenoverse 2 mod)

[Ken Kaneki 0005]

I've installed the goku ui mod (https://xenoversemods.com/mods/goku-ultra-instinct-transformable-dlc-6-v1-4/) and, as you can see in this video -https://www.youtube.com/watch?v=RYo24NYx_Hs&t=2s- he can use ui kamehameha, the one goku used with kefla. But the problem is, how do I put it in ui goku's moveset?
