Hor to wire this bluetooth module?

I am trying to make a bluetooth speaker and i got this bluetooth module from a shop How do i make it work?

Do i need to bridge the contacts(left side of the pcb in first picture between the soldered points)

The shopkeeper stated that it will run on 5v but it seemed to do nothing and didnt show up on my phone, i tried bridging the contacts with a pin and it threw tiny sparks but still didnt show up as a blt device

I tried google lensing it and found a board that looked identical and it was listed as 12v so i tried feeding it 12v. Still nothing. I tried bridging the contacts again and poof it went (Yes i burnt the ic)

I plan on getting another one but that will take time, meanwhile i would like to know how it is actually supposed to be hooked up.
