What is the bedtime for 3years old? My child comes from school at 6pm and only asleep by 10.30pm

My 3-year-old returns from school at 6:30 PM, followed by dinner and some screen time until around 7:00-7:15 PM. After that, we wash up and have playtime or do activities until 9:00 PM. She picks out her books for storytime while having her milk, and once both are done, she usually falls asleep by 9:30 PM, though sometimes it can be as late as 9:45-10:00 PM
