                          I'm trying to update my APN settings using:

    adb shell "su -c 'content update --uri content://telephony/carriers --bind name:s:\""SDR"\" --bind apn:s:"SDR-internet"'"

The first time I run this command I receive a superuser request from the package: com.android.shell. I can grant this manually but I'm hoping to automate the process for practice and knowledge. 

I've tried to use the following to list all permissions, but can't find superuser:

    adb shell pm dump package com.android.shell 
I attempted the following:

    adb shell pm grant com.android.shell android.permission.SUPERUSER
    adb shell pm grant com.android.shell android.permission.REQUEST_SUPERUSER
    adb shell pm grant com.android.shell android.permission.ACCESS_SUPERUSER
But receive an error:

        Exception occurred while executing:
    java.lang.IllegalArgumentException: Unknown permission: android.permission.REQUEST_SUPERUSER
    	at com.android.server.pm.permission.PermissionManagerService.grantRuntimePermission(PermissionManagerService.java:1398)

**Edit:**

I tried:

    adb shell su cat /data/adb/magisk.db

Which gave:

        SQLite format 3@

That's pretty ugly, so I tried using sqlite3 but it provides no tables? I was expecting a list of something at the very least. 

    sqlite> .mode line
    sqlite> .headers on
    sqlite> .tables
    sqlite> 

I'm using Magisk Manager v18.
