JB Kindle from 2024?

Hello! I have been considering jailbreak if my Kindle for a couple reasons, namely the customization options available through KOReader. I’ve been searching around for info on using Libby with a JB Kindle, but have found mostly info on older models. I almost exclusively read books through Libby. I borrow them through the app on my phone and send them to my Kindle. Would there be a way to do this on a JB Kindle? I’d be willing to get a dongle of some sort if it would have to be a wired connection, as long as it could be just from my phone to Kindle (no other computer involved). Thanks!
