Partecipating to Blitz Challenge after deadline

Dear all.

I am new to AIcrowd. While scrolling through the homepage I noticed a challenge about Iceberg detection that was really interesting to me. (AIcrowd | Iceberg Detection | Challenges)
However, when I try to partecipate in the challenge I get redirected to the page with only the active Blitz challenges. I don’t care about taking part in the leaderboard, I would just like to try my solution and see the accuracy. Is this possible or not anymore?

Thank you in advance
