Screen time limits

I want to add the Amazon Alexa app to “Always Allowed” on screen time. However, the app doesn’t show up on screen time at all. When I go to the always allowed section, the app isn’t there. And, if I go to App Limits > Add Limits, it’s not there either, under any of the categories. Can someone explain why the app just isn’t there at all? I’m sure I have the app installed; it’s being blocked during Downtime. But I can’t change find it in Screen Time at all. Has anyone had this problem and know how to fix it?
