Help finding simulacrum music !

Hi, as i said in the title, i'm looking for the simulacrum music only (in game when you activate the simulacrum with 300 shards ) , not the delirium ost( https://www.youtube.com/watch?v=JkE8VtxftgU ) .

Where can i find it? i 've looked in the Orman-Janowski youtube channel but can"t find the 'normal' or long version, thanks !
