As our content-script is not a module, that method will not work. I am trying to use this bit of code to load InboxSDK but keep hitting InboxSDK.load is not a function:
(async () => {
const src = chrome.runtime.getURL('pageWorld.js');
const InboxSDK = await import(src);
InboxSDK.load(...).then((sdk) => console.log('loaded'));
})();
