TL;DR:
I want to augment the komoot map with veloviewer tiles, e.g., paint a grid over the map that moves and zooms accordingly.
Unfortunately the JS of that page is minified and it’s not immediately obvious to me how to tie into that. How would I best go about this? What’s some advanced dev tools JS people use to figure this out? I know there’s some seasoned JS people here and I’m at the “if someone could point me in the right direction” stage, so have at it 
Thanks!
please excuse the ping: @zzq @narthur @bee y’all have way more JS and browser experience than me, any ideas?
P.S.: I’m back, beaches!
