Why can't I use "Save as" in playwright .NET

Question

When I connect to the browser via playwright, the shortcut ctrl + s does not work. Save as also does not work, while everything else works, such as ctrl + p.

        using IPlaywright playwright = await Playwright.CreateAsync();
        var resp = JsonConvert.DeserializeObject<dynamic>(response.Content ?? throw new Exception($"Connect browser error: content is null {response}")) ?? throw new Exception("Connect browser error: attempt to deserialize");
        IBrowser browser = await playwright.Chromium.ConnectOverCDPAsync(resp.ws_endpoint.ToString(), new BrowserTypeConnectOverCDPOptions());

All I do is connect to the browser. The save window just does not appear
