How to eliminate Snapchats Discover page from android phone?

[AC Question]

My 12 year old daughter has Snapchat and I find the content on the Discover page to be very inappropriate for her. I've read about people downloading the older version of Snapchat using an APK but it looks like all the methods that do this still allow the Discover page to be accessible by keeping the purple dot at the top tight corner of the stories page? Does anyone know how to completely eliminate it from app entirely?
