I am developing a custom Google Home device using Google Assistant SDK. I have developed custom actions as well for my device. Now I am at a stage of doing the production of the device. The problem is that I have to manually download credentials.json and put it into the device. For production, I want to use Google Home App instead of manually copying credentials.json, so that end users can configure the device using Google Home App. I am trying to figure out the way to do this in Google Assistant SDK documentation but unable to find it. So is there a way to use Google Home app for configuration of custom Google Assitant Device? Or Google Home App does not support it yet?
