Analysis of a chess position

https://www.chess.com/a/2XfGMSXMG2Ecfx

I saw this position somewhere on an instagram page. I got curious and I have been analyzing it since last 30 hours.

I tried to play as black against Max Level Computer(Rated 3200) on chess.com app and it always crashes. 

I shared it with my friend, who fortunately have diamond membership and he analyzing it using Depth 99. It shows it a dead draw.

I tried it on analysis board and the above chess game shows how it went. Can anyone help me if black can draw from this position, or can someone convince me that white can win from this position. I have tried to play most of the moves that black can try to draw with, but somehow white uses 'ZUGZWANG' and forces black king to rank 1. 

I would be very thankful if someone can convince me that white wins from this position. Thank you so much

This wins for white. First the white queen must drive the black king towards corner a1 out of the promotion square g3-g8-b8-b3 of pawn g3. Then white must sacrifice his queen for Bh3 and then queen pawn g3 out of reach of the black king.
