Good question @PogDuck123
Unfortunately the Good Lock App and it's plug in modules are available via region and eligible phone model.
Perhaps send feedback to the developer of the app via Playstore or via your Samsung Members App.
Be wary of using apk's as some can bring unwanted additional code and instability.
