i tried xev however im using ssh and any attempt on using stuff like MobaXterm dont work
You can use the command btmon to see live inputs. If you want to write inputs to a file, you can use btmon --write <path-to-file>, and if you want to read it you can use btmon --read <path-to-file>. It should come installed with bluez.
However, it seems that you want to capture keypresses of a pause/play button, similar to one that you would find on a keyboard. For that, the keybind is XF86AudioPause and XF86AudioPlay. For more information, check the Arch Wiki about Xbindings, as well as all the keyboard codes. If it's a keyboard code that's not part of xbindings, you can find them here.
