A short script but it will help you to debug your javascript/automation issues:
var allElements = document.getElementsByTagName("span");
total=0;
for(var i=0; i < allElements.length; i++)
{
if (allElements [i].className.includes("ng-option-label ng-star-inserted"))
{
// console.log(allElements [i].className);
console.log(allElements [i].textContent );
total++;
}
}
console.log("Total Item: "+total);
