How to handle pop up or notification in Macbook - selenium

Question

I want to get text of pop up using selenium webdriver.
Open URL https://ads.google.com/intl/en_IN/home/pricing/
Click on link 1800-419-6346* ( I am having xpath for this driver.findElement(By.xpath("//a[#class='eto eto-number']")).click();)
Now after click on above link , Here one Pop up is getting displayed which is showing message as “Open FaceTime?” .
How we can handle such type of pop up , I just know “Open FaceTime” is application which run on MacBook .
I tried to handle with alert class but it did not work.
Alert alert=driver.switchTo().alert();
System.out.println(alert.getText());
after running code ,I am getting message "no such alert"
Please note on Windows machine that popup will not be displayed, it is specific to Macbook.
My Code as below :-
public class Session1Mac {
WebDriver driver;
#BeforeMethod
public void setUp() throws InterruptedException{
System.out.println("enter into first method");
System.setProperty("webdriver.chrome.driver", "/Users/aturkar/eclipse-workspace/AutomateBSQATaskonMac/Lib/chromedriver");
driver = new ChromeDriver(); // launch chrome
driver.manage().window().maximize();
driver.manage().deleteAllCookies();
driver.manage().timeouts().pageLoadTimeout(40, TimeUnit.SECONDS);
driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
driver.get("https:/ads.google.com/intl/en_IN/home/pricing/");
Thread.sleep(20);
}
#Test()
public void VerifyRedirectingToDialer() throws InterruptedException, Exception{
// driver.findElement(By.linkText("800-419-6346*")).click();
driver.findElement(By.xpath("//a[#class='eto eto-number']")).click();
Thread.sleep(5000);
System.out.println("Element got clicked");
Alert alert=driver.switchTo().alert();
System.out.println(alert.getText());
}
}
Error on Console:-
Actual:-
org.openqa.selenium.NoAlertPresentException: no such alert
Expected:-I Want to get text of "Pop-up", if yes then how we can get it ? could you please help me with this.
