Client configuration file

Hi all,
Has anyone tried this, are there any examples where this is working?
What is best practice here?
Do all Traccar version support this?
Or should i build it from scratch?

I too am attempting to configure the Traccar Client using Headwind MDM. I have my application setup under the MDM and can push the Traccar Client manually to a device, but the configuration changes do not apply. The main options I want to update is status = enabled, url, and id. But setting the Attribute to one of these and the value to what I want to update it to does not work. I'm attaching a single screenshot as a referrence.
