try{

	// Set up the MutationObserver
	checkOOSStatus();//page load
	var observer = new MutationObserver(function(){
	    console.log("callback that runs when observer is triggered " + Date.now());
	    setTimeout(checkOOSStatus(),1200);
	    //console.log("mutation obs dk - " + dom_to_check.textContent);
	});
	// Start observing the document with configured parameters
	observer.observe(dom_to_check, {
	    childList: true, // Observe direct children
	    subtree: true, // And all descendants
	    attributes: true, // Observe attribute changes, as visibility could be controlled by inline styles
	    characterData: true,
	});
