Get GeoJSON files hosted on AWS S3 to work in Leaflet inside JavaScript

Question

Is there a way to call an AWS GeoJSON file from leaflet and not get CORS errors? I took the advice of putting "var Flight =" at the beginning of a GeoJSON file and saving it as JavaScript. I have a map that works when I call the GeoJSON (as .sj) like this

<script src="https://myflights.s3.us-east-2.amazonaws.com/2023_0322/images/2023_0322.js" type="text/javascript"></script>

and then later using it with the variable "Flight"

var leftPoints = L.geoJSON(Flight, {
      pointToLayer: function (feature, latlng) { 
         label = String(feature.properties.Name)
         return L.circleMarker(latlng, geojsonGreen).bindTooltip(label, {permanent: false, opacity: 0.75}).openTooltip();
         },
      onEachFeature: popUpLFeature}).addTo(map1);

my issue is when I try to change this using a variable to define the url: inside JavaScript and then trying to load the GeoJSON.

I have tried JQuery.getScript and $getJson but always end up with a CORS error.

Access to XMLHttpRequest at "https://myflights.s3.us-east-2.amazonaws.com/2023_0322/images/2023_0322.js" from origin 'https://my-test-2.azurewebsites.net' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

I have tried methods mentioned here - How to get Leaflet layer control to work with GeoJSON files hosted online but this seems to give the same result.
