IOS Dial Pad (Make A call)

Hi Guys,
I am new to iOS Appium.
How Can I lunch Phone dial pad in the iOS Phone.
It is fairly streight forward in android (capabilities.setCapability(“appPackage”, “”)).

Thanks for your help

I found one solution maybe helps someone else from hours of searching

iOS uses boundleId instead of appPackage

      cp.setCapability("bundleId", "");
