Trying to use a portable CD player - Any Bluetooth transmitter that will pair, or other CD solution?

I have a 2024 Prius Prime, I of course wasn't expecting it to come with a CD player but not a problem, I have a portable CD player with a cigarette lighter adapter. Problem is, I wasn't expecting there to be no aux input in this car! So I bought a cheap Bluetooth transmitter off Amazon, but the car doesn't see it at all when I try to pair. I'm not sure if it's the transmitter or the car that's causing problems, but before I waste money on a different transmitter, could anyone recommend one that will work, or any other simple solution they've found for playing CDs? I suppose I could get an FM transmitter in the worst case scenario but I'd rather not take the hit in audio quality
