I have the same problem here: when embedding my website (which contains the BotD library) with an iframe in another website and I open this one on the Samsung Internet Browser then my website doesn't load.

xnerhu commented 3 weeks ago

The difference is notificationPermissions, which in your case is true.

halidz commented 3 weeks ago

Can you explain why it comes as true? our case is we have our iframe embedded on another website. and when we open this website on Samsung Browser notificationPermissions value comes as true and it assumes as headless_chrome bot but its a false positive.
