Problems with frames in frames

[400ochkov]

Hello, I faced issue with frames, if website has frames which nested in another frames puppeeteersharp cant handle it.
I use code like

foreach (IFrame frame in page.Frames){Console.WriteLine("frame "+ frame.Url);}

and see only 2 frames when website has 6 frames each of them located in previous frame
Also I tried foreach (var childFrame in frame.ChildFrames) {} but doesnt help
I think it happened due to CORS

ps I work with antidetect browser, connect via ws
