Did Giuseppe Mazza help restore the last supper?

Giuseppe Mazza was not directly involved in the restoration of Leonardo da vinci's "The Last Supper." The most notable restoration was undertaken in the late 20th century by a team led by Pinin Brambilla Barcilon, which took place from 1978 to 1999. Mazza is known for his work in art conservation, but his contributions are not specifically linked to this famous mural.
