Good morning

my name is Igor Vitale and I am exploring the European Digital Credentials for learning. I am searching for the procedure for verifying our electronic seal. I see it's needed the NexU installed. Anyhow, when clicking I can't find the link for downloading the materials

Link: https://github.com/nowina-solutions/nexu/releases/download/nexu-1.22/nexu-bundle-1.22.zip

Do you know where I can find it or alternatively how can I verify the electronic seal? Thank you very much
Best regards
