Hitman 2: Silent Assassin - The Graveyard Shift Without disturbing office workers

Completion of the «The Graveyard Shift» mission in Hitman 2: Silent Assassin (2002). Challenge - Without suspicion, running and disturbing office workers. While performing the challenge without suspicion in this game, I tried to initially complete the level with this strategy in order to complete it with full stealth. But it was very difficult to do, so I refused and alarmed the office staff by running next to them so that they wouldn't react to the shot through the glass later. In the challenge, I also opened all the doors in sneak mode, always closed them, and never bothered office staff by slamming doors myself.
