Managed App Configuration with ionic


i have a ionic 3 app, and one of my clients asked me, if i can modify it to support managed configuration. I tried to search some information about it, and i found this plugin, but it seems quiet outdated :

Has anyone any experience with supporting managed configuration in ionic app? Iam looking for a solution for android. How exactly it works? It seems that i can get data from special config file, but where i get it? Do i have to create it manually or it will be created by emm provider?

Thx for any ideas.

It works, what features are not working?
