Shizuku

Shizuku is an app for running the Shizuku server in order to use apps that require this service, like App Ops. 'What is the Shizuku server?' you might be wondering. It's a process started either by root or adb that can invoke privileges that many apps don't have permissions for.

In order to use Shizuku on a non-rooted smartphone, you'll need to go through a somewhat complex process. Luckily, the app itself has a tutorial that explains what to do step by step. You'll need access to a PC and a cable to connect your Android smartphone to the computer.

Shizuku is a useful app for anyone who doesn't have a rooted smartphone but wants to use certain permissions that usually require root privileges. One of the best examples is the previously mentioned App Ops, which you can use with the help of this app even if you don't have a rooted smartphone.
