Apparently you can’t with the 8bitdo adapter (sorry made last post while half asleep) meant to link the mayflash NS2 which actually can pair both joycons
will link that here and change previous link in case someone comes across it later
You can use the Joycons with a PC using One of these
Looks like this has what you need
Looks like if you are lucky it might still be usable according to this diagram
The biggest difference is even when using dirty energy source electrice vehicles are more efficient at using the electricity from the dirty sources than gas engines are at burning gasoline directly
Looks like this shows it working with both joycons on a miniature laptop on the ns1 https://youtube.com/watch?v=aJU606gw-NM&pp=ygUVbWFnaWMgbnMgMiBqb3ljb25zIHBj
From the comments under the video these look to be the instructions to pairing both joycons to it
HERE IS WHAT YOU ACTUALLY DO:
1: Go to the Green mode.
2:Press the button once or twice untill the green led on the mayflash blinks really fast.
3:Hold the power button and the “hidden bumper thingy button” that is FURTHEST away from the controller until the controller either stops blinking or resets the lights. Do this for the one of the two controllers.
4:Repeat step 2 and 3 for the other controller (as in press the mayflash button until it blinks really fast), you will notice that the paired controller has shutdown and you can now do 3 to pair the other controller.
5:Press the mayflash button 2 times again so that it goes into fast blinking ( now all controllers have shutdown ).
6:While blinking press the power button on the LEFT joycon. Wait for it to pair with a solid green LED.
7:The mayflash must be now solid green and the left joycon too with the right NOT connected. GOOD … just press the mayflash button again so that it goes into SLOW BLINK and when it does hit any button on the RIGHT joycon AND IT WILL PAIR AT THE SAME TIME AS THE LEFT. CONGRATS
