The app finds and select the joycon but never pairs

Hi ! This is an incredible app and is the closest i got to connecting my joycon, but on Linux after launching the app it finds and selects my joycon but never pairs, after some modification of the code i could get the "Connecting" message to show up but nothing else. How can i fix this ?
