There is a better move, Rxh7+ leads to mate in 4

Nobody has pointed out yet that there is a button to the Analysis page (a small magnifying glass icon), where the engine answers every question.
In the last position, Ng3+ just loses. White plays Kg1, and now the white king is safe, while the black king is getting checkmated soon.

I started with bishop h6 check and after black did bishop g7 my move was pawn f6
Why chess.com thinks it is wrong? If black takes my bishop I take rook
Thank you in advance for answer

As I mentioned above, the Analysis tool is the small magnifying glass icon.
In this case, 1. Bh6+ Bg7 2. f6(??) Bxh6 3. fxe7 Kxe7 and the position is equal.
