Hey there!
Nice to meet you! I'm Darhyl, an Independent Advisor. No worries, let me help you sort this out.
According to the Microsoft official website, it is possible to set the screen time for any apps and games. Here's how:
Visit family.microsoft.com. Sign into your Family Safety account.
Find your family member’s name and click More options > Screen time.
Select Apps and games tab. Turn on App and game limits toggle.
Click the app or game you want to set limits on.
Set the amount of time your family member can spend on the app or game each day and when they’re allowed to use it. Use the same limits every day or tailor a schedule for each day of the week.
You may see an app or game listed more than once if your family member installed it on multiple devices. This is temporary until the data is processed. In the meantime, you can set a limit for each listing of the app or game.
