Where is Errol Flynn in ‘Lady From Shanghai’?

I just watched Orson Welles’ masterpiece ‘film noir’ ‘Lady From Shanghai” (1947) starring Rita Hayworth, Orson, and Everett Sloane. The ship in the film owned by the rich trial lawyer played by Sloane is actually the Zaca rented from Errol Flynn. Flynn is reported to have made a cameo appearance in the film but where? This is no trick question, I honestly couldn’t spot him anywhere. Where is he? Or is this just a legend? Thanks Ralph Schiller
