It's really just the chorus that's too high for her range, she should've just sang a few keys lower it would've sounded more pleasant. Otherwise it's a quirky fun song with vocals far better than her last 3 albums combined, better as a bonus track IMO.
It's a mix of Rih's Work and production of Ariana Grande (during Yours Truly days), first thoughts. Lemme not listen to snippets ever, I was so scared based on the vocals but uuuuh is the song great?! The spoken outro
