Homeassistant Core and Node Red ADDON

Hello! I’m running Home Assistant Core in a venv on my machine. Now I want to integrate it with the node-red.
I’ve installed Node-red, and connected it to the HA with node-red-contrib-home-assistant-websocket.

Now I want my node-red panels to be accessible FROM Home Assistant interface. I’ve read that it is possible on HA OS or Docker installation with “Node-red ADDON” installed.

But I can’t find it in my HA Core. So my question: is it possible to install this addon on HA Core, or maybe some other way to access node-red from HA Core interface?
