Using a Nintendo Switch as the touch screen

It goes without saying, you need a modded Switch in order to achieve this. More specifically, one that was prepared to (also) run Android. In my particular case, I use Android 10, but guess it will work the same way if you update to 11.
The original concept comes from a tutorial by AeliusDawn about running Citra on your PC using your main monitor as the top screen and a smartphone as a touch screen. While this is nice in its own way, there are two drawbacks here.
First, the screen size, depending on your device, may be kinda small (though I guess you could use a tablet too?) unless you have a flagship or a rather newish phone. Yes, I know the touch screen on the 3DS is kinda small too. But why stay small when we can go big?
And second, a smartphone/tablet lacks buttons, forcing you to still use your keyboard or a joystick, making the experience actually worse cause now you need more peripherals to play the same games, making this more a proof of concept than something actually viable to be used in normal basis.
So, following the tutorial by AeliusDawn, I got everything ready on my PC and my Switch. In order to be able to use the joycons, I had to individually synchro both of them with my PC and map the buttons inside Citra.
The problem here is, once the joycons are attached into the console, they automatically turn off any kind of bluetooth signal and forcedly synchro back with the console (doesn't matter if you're on Android or Horizon on sysnand or emunand), so you have to detach them in order to use them. Or, if you're like me and wanna use them as a console, simply lift the joycons a little but leave them in the rails. As long as the contacts on the bottom aren't touching with the ones of the console, the joycons won't automatically synchro back. You can see I'm struggling a little to keep my right joycon in place cause the rail is wasted (I can take the joycon off withot pressing the back button to release it), but the left one stays in place just fine, so you won't have any problems if your console is in a better shape than mine (also, to be fair, I was in a really uncomfortable position, with my phone recording just in front of my face and my arms around the tripod, but I don't have that many problems when I'm sitting like a normal human being).
