Amazfit Watch faces

hey all,

I just got my T Rex 3 and using the @SashaCX75 tool I converted this watch face from GTR3 to TRex3:
https://amazfitwatchfaces.com/gtr/view/28667

So now I have the .zip file, but can't find how to send it to the watch.

I've tried having the .zip file in the phone and opening it with AmazFaces app, but it stays in 'Loading' and have a button message that says "Change to UA" but nothing happens.

Any help you could give me is appreciated!

Thanks!

This is the screen I see and stays there:
