Meltwater Champions Chess Tour PGN

Does anyone can share a pgn with movetime or timeleft after move info of the past Meltwater Champions Chess Tours like Skilling Open, Airthings Masters, Opera Euro Rapid and Magnus Carlsen Invitational. Just the prelim games are enough. I would like to generate time pressure stats, etc.
