title: How to check if notifications is already allowed by user in google chrome?
body: <p>I have a modal that pops up first asking if the user wants to receive special offers, if they click yes, then I pull in the code for push notifications so that they can allow notifications.  If they already allowed notifications I don't want the modal to pop up.  I am looking for a way to check if notifications has already been allowed by the user, using google chrome.</p>
