How to access the app battery optimization settings on Android 12 and above?

The menu appears to have been hidden on the more recent Android releases — currently on Android 14 the only per-app toggle the users are given is 'allow background usage' (app info → app battery usage). On my Oneplus 8T device the OS is actively stopping some apps designed to be running on the background at all times, such as Shizuku . On AOSP-based ROMs three settings used to be available for each app, the most permissive being 'unrestricted'. SystemUI Tuner didn't expose the menu. --- Using ADB is an acceptable answer as well.
