He may have been involved but based on the court documents his involvement wasn't criminal.

"Mr. Campanella denied any role in the procurement deal on Monday, saying he had only put Mr. Romano in touch with a hedge fund that had masks. “I did not make any offerings or any documentation to offer anything to New York City,” he said. He did not respond to telephone messages on Tuesday after the criminal complaint was made public."

Was Nick Campanella Named in the court documents of the case?

Was Nick Campanella charged with any crime in that case?

So it appears that while he may have been a part of the process his actions were not criminal hence the court protected the innocent man identity by not naming him in the official court documents.
