The attribution that Siradel specifically built the digital-twin layer (rather than just being a general consortium member) is an inference from Siradel's placement on this specific page, reinforced by outside reporting (not one of the entry's four sources) that credits 'Siradel and Meersens' with designing the Paris2Connect digital twin.
