Getting Authorization error whild setting up warp 1.1.1.1 as device admin app

Question

I am trying to set an app as a device owner/admin using the ADB shell command on a non-rooted Android device. The app package name is "com.cloudflare.onedotonedotonedotone."

I have used the following ADB command:

adb shell dpm set-device-owner com.cloudflare.onedotonedotonedotone/.com.cloudflare.onedotonedotonedotone.MainActivity

However, I am encountering the following exception:

java.lang.SecurityException: Calling identity is not authorized
    ...

I do not want to root the device, and I understand the security implications. Are there any specific permissions or steps I am missing to set an app as a device owner/admin without rooting?

Any guidance or suggestions would be greatly appreciated. Thank you.

Tried this :

adb shell dpm set-device-owner com.cloudflare.onedotonedotonedotone/.com.cloudflare.onedotonedotonedotone.MainActivity

Error :
