Not able to close advertisement popup

public class MakeMyTrip {

public static void main(String[] args) {
	WebDriverManager.firefoxdriver().setup();
	WebDriver driver = new FirefoxDriver();
	driver.manage().deleteAllCookies();
	driver.manage().window().maximize();
	driver.manage().timeouts().implicitlyWait(Duration.ofSeconds(10));
	driver.get("https://www.makemytrip.com/");
	
	WebDriverWait wait = new WebDriverWait(driver,  Duration.ofSeconds(20));
	wait.until(ExpectedConditions.frameToBeAvailableAndSwitchToIt(By.id("webklipper-publisher-widget-container-notification-frame")));
	
	WebElement closeButton = driver.findElement(By.xpath("//a[@id='webklipper-publisher-widget-container-notification-close-div']/i"));
	closeButton.click();
	driver.switchTo().defaultContent();
}

}

In my code, I switched the frame and then tried to close the advertisement. The click is not working and not getting errors in the console also.

Use JavascriptExecutor.

Try with this code :-

	WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(20));
	wait.until(ExpectedConditions.frameToBeAvailableAndSwitchToIt(By.id("webklipper-publisher-widget-container-notification-frame")));

	WebElement closeButton = wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//a[@id='webklipper-publisher-widget-container-notification-close-div']/i")));

	JavascriptExecutor executor = (JavascriptExecutor) driver;
	executor.executeScript("arguments[0].click();", closeButton);

	driver.switchTo().defaultContent();
