hi. i'm using a d850 on my LB2/N3 setup, which is pretty similar to the setup of the M600.
i don't think that tapping on the screen will trigger the shutter, but in my case i've set up the shutter button on the LB2 remote control to trigger the shutter.
the setup is much as you've described it, here's the detail of how i do it.
d850 (d810) camera is connected via HDMI cable to the HDMI input of the LB2. (lightweight mini -> micro hdmi)
F2 port of the N3 is connected to an "rc to nikon" shutter adapter. the adapter requires power too, so in my case i connected it through the aux port of my gimbal (gremsy t3) which adds power. https://forum.dji.com/thread-134231-1-1.html
before taking off, turn on live view on the camera, and set to the appropriate mode. personally, i put it in M (manual) with a shutter speed of 1/500, aperture between 1.8 and 4.0 depending on lighting, and auto-iso which guarantees good exposure. i typically position the focus point below center. you won't be able to move it in flight. i also like to use bracketing with a stop plus and minus, and i often set the EV to -.3 or -.7. these cameras have so much DR (much more than anything DJI makes) that it's not a big deal if you under or over expose a bit, but i still like a clean raw file.
you ought to see the video feed on your tablet connected to the remote controller. when you hit the shutter it will focus and take the picture.
unfortunately these are SLR cameras, so the image will black out for a second while the shutter fires. best to do this when the drone is not moving!
in my experience with the LB2 and D810, the quality of the video feed was not very good, and there were frequent "refresh" pauses on the display. shutter blackouts were long. the d850 does much better.
there may also someday be intelli-g support for the d850 and d500, which would allow setting aperture and so on in flight.
it's also too bad nikon doesn't include the cheap infrared sensor on the pro cameras. the front facing IR sensor of the D7500 etc could be used to trigger the camera more easily than a physical connection through the gimbal.
