Snaps to develop a Web kiosk on Ubuntu Core (using Wayland)

@greyback I want to give this a try, and I was checking the source code of the chromium-mir-kiosk, which I understand is here:

In the code the chromium version is still 72.x, but on the store the latest available version is 76.x:

$ snap info chromium-mir-kiosk
name:      chromium-mir-kiosk
...
channels:
  stable:    –                                   
  candidate: –                                   
  beta:      69.0.3497.100 2018-09-26 (35) 163MB -
  edge:      76.0.3809.100 2019-08-20 (64) 174MB -

So I was guessing, where is the latest code for the snap?

Thanks!
