Uworld addon for step 2 with v12

For the Step 2 Uworld addon, the search Anki for missed cards button appears on Uworld, but I do not see any cards in the Anki browser. I am using the latest version of Google Chrome on mac, AnKing v12 via Ankihub. Can you help me?

Can you elaborate on what you mean by do not see any cards in browser?
