I can help you.
I can explain it to you,
1= Download LsPatch (version 0.7 if you have Android 15, 0.6 if you have lower versions.) and Shizuku on your phone, set up Shizuku (just look up a tutorial online), and authorize it in the "Authorized Application".
Open LsPatch, and in there is "Shizuku service available", that means it's working.
Download this module from here, install the APK, then go to the play store, install ZZZ.
2=Go to the developers options on your phone, go down until you find "Reset to default values" tap it multiple times until the option "Turn on system optimization" can be seen, turn it off. You can turn it on after installing the patched game.
3= Use Zarchiver or any other file opener, crate a new folder and name it LsPatch, put the module in it. Open LsPatch, go to the "manage" section, press the + button, choose the folder that you created and then "select an installed app", select ZZZ, press start patch, and that's it, its installed.
Long press on it in the manage section, press "module scope", and make sure that the module is selected.
