Try Canon Camera Connect
I did. Sometimes it works, sometimes it doesn't.
I think that's the definition of magic.

I do a lot of astrophotography, and for the most part I use Canon Camera Connect on my Android (LG K92) phone, it works very well to release the shutter and start and stop 4k video without introducing any shake of any kind. I use 4k video for solar/lunar/planetary imagery, taking 2-3 min of video which results in several thousand frames for stacking.
The only trouble I have is that I have multiple bodies, and the Canon Camera Connect app 'sees' all the bodies even if they are turned off and 20 feet away in the house LOL so I have to make sure I am connected to the 'right' camera I have hooked up to the telescope!
It is an issue when I'm actually shooting with more than one body at a time, sometimes one on a telescope for which I'll use the app, and a second on a tripod, for which I'll use the touch screen shutter and self timer. With the M6 mark ii you can use interval timer or focus bracketing to shoot many images unattended, but I'll start it with the touch shutter.

I use the M6 Mark II for full-disk solar and lunar imagery, but for extreme magnification solar/lunar/planetary I use the M200 with 4k video and a 2x teleconverter, since the M200's crop factor gets to the 'pixel level' on a 4k video with IS turned off, which is a closer crop that the M6ii's full sensor width (probably line-skipped) video. Also the M200 is somewhat smaller and lighter on the scope than the M6ii body which may reduce help vibration, especially if there's any wind.
