I dont understand how to add custom config to my app with android

Hi there

I am struggling to understand how I can add custom config to my app on android so that when users download the app from intune, the config automatically is passed with the installation.

The config is a key/value pair:

qrCode: "{"applicationName":"LoremIpsum","baseUrl":"https://LoremIpsum.com.au/01/api/mobile/"}"

acceptTermsAndConditions: true

The qrCode value is a string

The acceptTermsAndConditions value is a boolean

I have managed to get this working with ios very easily. Ios app config provides a nice UI to add key/value pair (first image). Android (second image) however does not provide this UI to add config and I dont understand why. Appreciate if someone can tell me how to get android config to be entered like ios that would be amazing.
