I want to know how to accept the dialog?

await page.WaitForExpressionAsync("window.location=='http://localhost/a.html'");

await page.ClickAsync("#btn");
//await page.Keyboard.DownAsync("Enter");
//await page.Keyboard.UpAsync("Enter");

//await page.Keyboard.PressAsync("Enter");

///no trigger for below code
page.Dialog += async (_, dialog) =>
{
if (dialog.Dialog.DialogType == DialogType.Confirm)
{
// 模拟点击确认按钮
await dialog.Dialog.Accept();
}
else
{

     await dialog.Dialog.Dismiss();
 }

};

You should attach to the Dialog event before performing the actions.
