Get item quality from chat link

[scootter]

I have been slowly learning as I go but for some reason I am having a roadblock on this particular one and can't even get started. I am having issues with all items that people post in chat but the main thing I am trying to get is the items' quality from the chat link. I am at a loss on how to do this. If someone could give me a gentle nudge in the correct direction I would very much appreciate it.

Thank you!
