How to push known api auth clientid's and secrets using IC2


I have a customer that wants to deploy a bunch of MAX devices in vehicles in combination with tablets carried by staff that have an app that connects using the device API.

They want the tablets to work when they move between vehicles with zero user interaction when it comes to authentication.
So they have asked for the same clientId / clientSecret to be pushed to all the devices in a group.

That doesn’t look like its possible since the client ID and secrets are not stored in the config file, so can’t be applied using the bulk configurator.

So what is the right approach here? Can we get IC2 to generate api auth credentials maybe?
