I see, Yeah this is a real bummer as I found this camera used mostly for Vlogs and used by many YouTubers i figured it'd have the capability to use on my computer with live remote viewing.
I seriously appreciate your research and well that's even worse that even magic lantern don't support EOS M3.
Even if it could be remotely controlled, the battery is a bit small for extended video work. I do not think there is an AC adapter available, either. You need a video camera, or at least a camcorder.
As previously noted, you have a camera designed first, and foremost, to take still photographs. Making videos is not a priority, but rather a bell and whistle. Most DSLRs and mirrorless cameras have a tendency to overheat during extended use in video modes, anyway.
