Advice for configuration HA + RoomAssistant

Hello guys, I have one old laptop and Home assistant installed as Supervises. Everything is ok, bu i want to install Room Assistant as well. How should i do this, as an Add on to some assistant, standalone with NodeJS or any other way.
At the moment I have tried only as an add on, but I don’w know how to configure it to work with Home Assistant and detect laptop Bluetooth.
