Divinity Original Sin 2 — norbyte's script extender

DOS2 has a native mac app, but many/most QoL mods require Norbyte's Script Extender which is win-only. I've been attempting to get it running via crossover (read: I followed install instructions, have no idea what other steps to attempt) but am receiving an error "cannot create a working story."

was wondering if anyone had navigated this, if it was even navigable
