You can actually get by without root by using Frida (https://frida.re/docs/android/ https://frida.re/docs/android/), at least on Android. By repackaging the APK to include frida-gadget (such as in this tutorial: https://koz.io/using-frida-on-android-without-root/ https://koz.io/using-frida-on-android-without-root/), you can get all of Frida's capabilities on that app without root. That said, it is more convenient to have a spare rooted phone.
