I reached similar position ( but black forced give a7 pawn and white wins pawn wins the game but not so easy ( Rook+pawn vs Bishop of Wrong Color)you know rook+pawn vs wrong color bishop is draw generally but at this position black made a mistake to allow cut his king
and it's losing I will notice it white can't take a7 pawn draw
