    public_key_y,
    // [u8; 64] - signature generated by `credentials.get`
    signature,
    // BoundedVec<u8, 256> - clientDataJSON generated `credentials.get`
    client_data_json,
    // BoundedVec<u8, 64> - authenticatorData generated `credentials.get`
    authenticator_data,
    // [u8; 32] - challenge generated `credentials.get`
