I downloaded the APK and then used "Profile or Debug APK" under file in Android Studio and ctrl/cmd+shift+f to search for strings.

I don't know much about Android development or APKs but it's not exactly "reversing." from what I understand the profile/debug converts the .dex files from the APK to .smali which is human readable.

You can use the "Analyse APK" feature, but you probably rather want to use tools like jadx or apktool that provides fairly good decompilation.
