Recovering data from thunderbolt hard drive

Hello, I had an external monster thunderbolt drive I used in college that had all my data predating 2018. One day it was working the next day it was not. The drive had a built in thunderbolt cable (I know, lesson learned). It would light up but it wouldn't mount on to any computer. I sent it in to werecoverdata.com they weren't able to recover it at that time in 2019 and sent it back, it had been opened. The company who made it, monster digital, had gone out of business around that time already, so I couldn't go to them for help. I'm still holding on to the chance I can figure out a way to recover it. I don't know if the recovery people tried but I recently thought about probably putting into a new enclosure. I'm not even sure where to begin. If anyone has any suggestions please let me know. I linked the exact drive from B&H Monster Overdrive. Thank you in advance for your responses! any help is appreciated!
