That's from Wayfinder's Guide to Eberron and/or Eberron:Rising from the Last War. You need to own the sourcebook (or own that magic item from it), and have Eberron Content enabled in your HOME | Preferences.
I have Eberron Content enabled, but I do not own Wayfinder's Guide. I am in a campaign whose DM is sharing Wayfinder's Guide though, so I have access to the book.
Can I only use content from Wayfinder's Guide on the character in that campaign? That could be the problem since this is for a different character.
When choosing the Replicate Magic Item Artificer infusion, the common magic item Feather Token (Feather Fall) does not appear in the list.

Correct, you only have access to shared source material in the Character Builder if your character is in the campaign sharing the material.
