How to make any native know to use document.currentScript.src or import.meta.url

I have no control how a 3rd party loads my scipt.

Can be <script type="module" src="myscript.js"> or <script src="myscript.js">

When not loaded as “module” the code inside my script always errors with:

Uncaught SyntaxError: Cannot use ‘import.meta’ outside a module

This SO answer “Uncaught SyntaxError: Cannot use import statement outside a module” when importing ECMAScript 6
is not an answer for native/vanilla JavaScript without bundling.

Is it possible at all to test for “module” inside a non-module script?

A simple if does not work:

    let myURL = "";
    if (document.currentScript) {
        myURL = document.currentScript.src;
    } else {
        myURL = import.meta.url;
    }

Try-Catch does not work:

    let myURL = "";
    try {
        myURL = import.meta.url;
    } catch (e) {
        if (document.currentScript) myURL = document.currentScript.src;
    }

You-know-who and You-know-Elon-who come up with variations of above code that do not work, causing the error
