Proper forum to ask about prototyping a Matter over Thread device using Alexa / Amazon Echo with Thread Border Router

I’m finding sparse information on Matter development on Amazon.

I have an nrf5340dk development kit which I can flash with standard Matter IOT device examples (e.g. door lock, light bulb).

The door lock fails without any sort of searchable error message.
The light bulb nearly pairs successfully until the error message “This device is not Matter certified” pops up.

I don’t intend on using the Amazon Connect Kit which probably already solves my problem. I would expect there is some method for product developers to use uncertified Matter devices during prototyping.

Is there a proper forum on Alexa/Echo IOT device integration?
