How to get 'SuperView' on the Osmo Action

One of the great features that GoPro has, and that the DJI Osmo Action camera HAS NOT GOT, :( is 'SuperView', which gives a very very wide field of view, great for action footage when you want to see as much as possible around the camera.
But I figured out a way to get this extra wide field of view and correct for the 'squashiness', which closely matches the in camera effect that 'SuperView' gives GoPro footage.

Also, here is my review of the Osmo Action, hopefully you find it fair and covers all the main points.-
