Offer Decisioning : Post Decision received how one can display the content ?

Hi Experts,
I got a website & I simply want to show an offer content [basically just a simple text msg] on it.
AEP side I got offer & activity in well shape which I can execute via postman api call for certain profile. Everything just works fine.

Challenge is on Launch side when event is getting sent while offer evaluation on home page, my decision received event gets trigger but I have no clue how can I retrieve offer contents via custom code. ?

I found one , but its for web image & for web image it doesn't work unfortunately.

event.decisions.forEach(function(payload) {
payload.items.forEach(function(item) {
console.log(">>>>> Offer Decisioning Web SDK Response", item);
document.getElementById("brandhero").src=item.data.deliveryURL;
});
});

I have no clue if my offer extraction is working well. NO way to verify/debug.
