How to add left hand accompaniment for this song- always with me from Spirited away (violin sheet music)

My daughter is a piano beginner. She watched <Spirited Away>, she likes <Always with Me>very much. But the piano sheet music is too hard for a beginner. One day I heard she was playing the song <Always with Me>, actually playing the violin sheet music as follows. I think it is not bad idea for her to play the violin sheet music which is much easier than piano sheet music. The problem is how we can add the left hand accompaniment. I watched Youtube, someone taught us to add Arpeggio. Can anyone please help me with this? Can you add the simple left hand accompaniment for the sheet music? Thank you so much!
