How to create a Matter-enabled certs?

[DmitrySysoletin]

Hi!
I want to test an ESP Rainmaker Matter-enabled example with the private Rainmaker deployment. However, I can't find a way to create certs that will work with a Matter-enabled Rainmaker example.
When using a Rainmaker CLI, we can do this by adding a --matter key.
How can I do the same, but for the private Rainmaker deployment (with esp-rainmaker-admin-cli)?
Thanks in advance.

Please check out this Manufacturing Considerations section in the Matter examples for info about this.

Thank you, it was helpful. Now I can at least flash the device and it will not stuck in a endless reboot cycle.
However, I can't provision it with app (https://github.com/espressif/esp-rainmaker-android) - it says "Invalid QR code". In the same time, Rainmaker APP from the Google Play accepts this QR code, but because I want to test it with a private Rainmaker cloud, I need to use a custom app, I guess.
How can I perform commissioning of this Rainmaker+Matter device?

P.S. In QR Code that custom Rainmaker app accepts, we have JSON like this: " {"ver":"v1","name":"PROV_6d5bac","pop":"2fabd885","transport":"ble"}". In Matter+Rainmaker QRcode (generated bt mfg_tool), we have only short string of numbers divided by dots. It seems like a Rainmaker APP from Google play supports both format, but opensource version only supports Rainmaker-only, but not Matter format.
