This feels like a dumb question, but I can't figure it out. I see posts saying that there should be a button called 'Feed' which takes you to their stacc feed, but I can't find anything like that.

I imagine the reason it's not showing up is due ro not being logged in. (I just use the bookmarklet tbh, it's like magic. See forum #328510 and forum #328678)
Danbooru will fetch the stacc for you when creating a new artist entry, try putting one of the artist's links into here. Alternatively if you can find their sketch (usually at the bottom of the page, if available) it'll be the same name.
You can either use user #433258's bookmarklet, or just replace the /user/ part in profile URL with /stacc/id/ (i.e. https://www.pixiv.net/users/123 -> https://www.pixiv.net/stacc/id/123).
