I'm trying to evaluate Matter network for the first time. I'm using the following:
- 1x Laptop with Ubuntu 20.04 with OTBR using Docker installed by following step by step the guide: Matter over Thread: Configuring Border Router and controller on one device .
- 1x NRF52840 USB dongle flashed Thread: Co-processor sample, and configured with overlay-usb.conf and usb.overlay from NRF Connect v2.3.0. The Co-processor is configured successfully using the step2 in the guide.
- 1x NRF52840 DK flashed with Matter Door lock sample from NRF Connect v2.3.0.
When I run the docker image using the following command I get the following log regarding the RCP API version:

How I can change the RCP API version? Should I downgrade the NRF Connect SDK version for the CO-Processor sample and flash the USB dongle again? Or should I do a change for the docker image?
