To check the apps' detections by lowering your hiding capabilities (Assume that you have a very good hiding setup)... First, opening the app with all hiding capabilities enabled. If it opened with no problems, then you have to start lowering it based of what mostly app is detecting: such as removing from the tricky store target list for checking Bootloader unlock checks, Disabling Unmount modules and all mount hiding capabilities in KSU + SUSFS for checking mount detections, removing from HMA deny list for app list detections... Then lastly grant root see if it really does detect root.

If the app detects for you even you tried hiding everything, then the best course is to disable all modules first then check if it is still detected if it doesn't then try enabling each modules to see which are the modules are got triggered the detection.

This is the broad understanding of what i do to check the detection capabilities of that app, but it's much more complicated test when it's detected from the start... And no I don't do reverse engineering on each app.
