Hacking an LED Mask

I am very excited to start a new project that charts extremely unfamiliar territory for me. Specifically, I bought a cheap-ish LED mask from Amazon and I’m really interested in uploading custom images to it for fun (and clout on social media.) Now I haven’t actually received the mask yet, but I did some research on the app it uses which uses Bluetooth to connect to the mask and transmit data to it.
