I have the same problem - what is service name for resetting the location permissions in macOS 11.1? Is there a list with all the available service names?

I have exactly the same problem - although all information in the .plist file and the localized InfoPlist.strings files is there, my app gets rejected and I don't know how to reproduce the issue. Does anybody knows a solution for this?

This can be done by adding an macOS plugin which has access to the whole AppKit API.  Then you can set the desired appearance there at runtime, for example: NSApplication.shared.appearance = NSAppearance(named: .darkAqua) For more information please see this StackOverflow question: How to set dark mode for NSToolbar in macOS Catalyst app?
