How to find out permission values ​​in AndroidManifest?

Question

Android

Android 8.1 device, LG Nexus
There is one app that gives out free food coupons.
But it only shows up on one device.
I want to bypass this lock and get a lot of food, please help.
I reflash my cell phone, insert a new SIM card, change IMEI, change MAC addresses and another ip address, of course.
But they recognize me.
How can I find out what data the application is using to fire me?
I looked at AndroidManifest.xml for access requests, this is what I got in response:
