How to get Coinbee 2 working?

Hi can anyone please supply a step by step guide on how to get CoinBee 2 working? I watched this video: ConBee 2 with Home Assistant - YouTube but I don’t have anything in my left hand column that says Has.io/

The video is over 2 years old, it’s horribly horribly outdated.

If you’re using Home Assistant OS then just follow the docs and install the deCONZ add-on, and integration.

OK so I did that. I installed the intergration. This part was easy. But how to I add any Zigbee devices to my Home Assistant instance? Thanks.

It’ll be done in the deCONZ/Phoscon UI. I don’t use it so I can’t help there.
