Nagy Fathy, any idea why that was a draw?

Game 2229928. Really puzzled by what happened, still trying to learn the game though

Unless you both agreed to draw that seems like a mistake to me. The game could easily continue.

My guess is that before sending your 47th move, you inadvertently clicked the "offer draw" box before sending, and then Nagy Fathy accepted your draw offer on move 48.  If true, then that was truly an unfortunate "misclick"
