I know, you need to do more but I mean what pin we need to short, because I know for RCM after short the pin you have to press the volume up I think and then connect the switch to a pc via USB and a few things more, for The pegaswitch I don't know but I just ask for the pins haha
You have to ground PIN 10 on the right JoyCon rail and press VOL+ during boot to enter Tegra RCM mode.
