Is There A Way To Downgrade The Apple Reminders App?

Is there a way for me to reverse the update for the Apple Reminders app that was added in iOS/iPadOS 13, WatchOS 6, and MacOS 10.15 Catalina? I only ask since my iPad only gets up to iPadOS 12 and I can't use it with the rest of my devices, it is or was the main device I managed my reminders on and would like a way to go back top the way it was. :(
