I'm trying to automate interaction with Microsoft Copilot, but I'm unable to click the Cloudflare Turnstile captcha that appears. The captcha is embedded within a shadow DOM, and my current approach using sb.cdp.gui_click_element('#cf-turnstile div') isn't working.

My code:

from seleniumbase import SB

def generate_response(prompt):
    with SB(uc=True) as sb:
        url = "https://copilot.microsoft.com/"
        sb.activate_cdp_mode(url)
        
        # Handle initial 
        combined_selector = (
            'button[data-testid="chat-mode-switcher"], '
            'button[data-testid="composer-chat-mode-quick-button"]'
        )
        sb.cdp.wait_for_element_visible(combined_selector, timeout=30)
        sb.cdp.click_if_visible(combined_selector)
        sb.cdp.wait_for_element_visible('button[title="Think Deeper"]', timeout=30)
        sb.cdp.click_if_visible('button[title="Think Deeper"]')
        
        # Find prompt area and type
        prompt_area = "textarea#userInput"
        sb.wait_for_element(prompt_area, timeout=30)
        sb.cdp.wait_for_element_visible(prompt_area, timeout=30)
        sb.cdp.set_value(prompt_area, prompt)
        sb.cdp.press_keys(prompt_area, " ")
        sb.click('button[aria-label="Submit message"]')
        
        # Handle captcha and wait
        sb.sleep(2)
        sb.cdp.gui_click_element('#cf-turnstile div')
        sb.sleep(120)
        
        return None, None

generate_response("Test")

Image for ref:

sb.cdp.gui_click_element('#cf-turnstile div') does not work on clicking the captcha, even though on CF Turnstiles, I use the parent selector that appears above the #shadow-root element, as shown in your example on the doc.

First, you should upgrade to 4.41.11 (or newer if available).
And then run SeleniumBase/examples/cdp_mode/raw_copilot.py.
It's a test that runs on the Copilot website, and it's working for me.
