ISO the right sound for cover

hey yall - i'm hoping to emulate/ mimic the sound of the synth(?) in Rina Sawayama's This Hell. I'm looking to just play the F-G-Am on lead mode while my guitarist plays the riff on lead guitar.

Wondering if anyone thinks there's a particular sound preset that would work best for this or if i need to go about creating my own sample.

About to butcher describing it but it's almost a mix between Zen/Orba/Ohm but with a more metallic and guitar vibe? youtube video here: https://www.youtube.com/watch?v=ekauErew4Bs
