I would also ask if she wants to perform more? If not, it's really not a big deal. Plenty of people enjoy playing piano just for themselves. If she wants more performances, I think the first thing is to talk to her teacher and see what opportunities she is aware of locally. Maybe the teacher can host more recitals if a number of her students want this; maybe there are local festivals or joint recitals by a few piano teachers; maybe your child can enter exams/competitions etc. Playing at nursing homes is a great ideas almost in any community. There are lots of opportunities if you explore.
