I have cookie popup from here:

website

which I selected with shadow-root like this:

howto

now I want to click the button with xpath expression like this:

        WebElement shadowHost = driver.findElement(By.id("usercentrics-root"));
        SearchContext shadowRoot = shadowHost.getShadowRoot();
        WebElement shadowContent = shadowRoot.findElement(By.cssSelector("button[data-testid='uc-accept-all-button']"));



        shadowContent.click();

But selenium always gives me:
org.openqa.selenium.NoSuchElementException: no such element: Unable to locate element: {"method":"css selector","selector":"button[data-testid='uc-accept-all-button']"}

How to click the button right?

I am expecting the CSSselector button[data-testid='uc-accept-all-button'] to select the button inside of shadow-root.

Looking for CSSselector “class” sc-dcJsrY.fMlgSq has the same “unable to locate element” error.

One more question is: can I verify the CSSselector inside of shadow-root in chrome inspect, too? Searching for the CSSselector in chrome inspect gives zero occurrences.

I read here that xpath isn`t supported so I switched to CSSselector:
