Thank you @TravellerG for tagging me.
@PrasadVR, here’s the answer to your question. We keep a running list where you can find in the first few comments on this topic. For any challenge wins in between (two, four, six, seven, eight, and nine).
Ten is the maximum for now and we currently do not publish their name anywhere else after you pass the 10th win, though we still track it internally.
Hope that answered your question.
