Eufy security integration issue

Hi I have a eufy E30 outdoor light that I want to integrate with home assistant.
I’ve got the eufy security hacs integration working on HA with the exception that I can’t get the camer to actually stream.
In the installation guide I’m all good until l get to 4 setting up the dashboard for camera, I see I have to add some YAML coding, but for the life of me I don’t know where this is supposed to be added, everywhere I have tried to add this code hasn’t worked
Could someone be so kind as to point me in the right direction as I think this is the missing piece to camera integrated and streaming.
