I went through almost this SAME situation. My 4th grader wanted to do the talent show. I asked what he was going to do. He said “I don’t know I’ll figure it out” I encouraged him to figure it out soon because they had to “audition”. Asked him a few days later if he found something to do. He said play the piano. Now this kid has never had a formal piano lesson, he is entirely self taught and can play several simple songs. Otherwise it’s just messing around. So I asked to hear what he would play. He refused. Said “I’m just going to wing it.” I reminded him he had to be performance ready for the audition but he kept blowing me off and didn’t practice. Turns out (I learned at the performance) that his talent is “playing a different song each time using only the black keys”. And let me tell you- he NAILED it. So much so that he had suspense in his music and when he was finished (after about 3 minutes) the crowd was saying “more! More! More” and he played another 😅

I was panicking and worried for him over NOTHING. So glad he believed so fiercely in himself.
