Could you share the flow if someone wanted to replicate it for their own Kobo?

Yes, but it currently depends on Pocket working.

I have an RSS feed from RoyalRoad that new episodes come in on. Using IFTTT, I have an action set up to, whenever a new item comes in on that feed, add the _URL_ of it to my Pocket account. Then, Kobo just syncs the Pocket articles automatically, and the new episode is added.
