Alert Hello World in UXP

[Ghoul Fool]

Not so much jumping into the deep end but going swimming with cement flippers with UXP, I try to create an alert in InDesign .injs:

alert("hello!");

I get an alert of sorts...

But not quite as friendly as I'd hoped.

I can get around it by writing a bespoke alert function as mentioned in this recipe here.

However... it says here that Since UXP v7.4, `alert()` can only be invoked in `plugin` via the featureFlags `enableAlerts`. Update your Manifest v5 with the following:

so I've updated  the manifest:

{
  "id": "myUniqueId",
  "name": "Hello Worldplugin",
  "version": "0.0.1",
  "description": "Description goes here",
  "summary": "Summary goes here",
  "host": {
    "app": "XD",
    "minVersion": "13.0"
  },
  "uiEntryPoints": [
    {
      "type": "menu",
      "label": "Create Rectangle",
      "commandId": "createRectangle"
    }
  ],
  "featureFlags": {
     "enableAlerts": true
 }
}

based on the Developer Starter project - so ignore references to rectangles. But get the same error as above.

So what's going on?

"host": {
  "app": "IDSN",
  "minVersion": "19.0"
}

If it's still not working

async function showCustomAlert() {
    const modal = document.createElement("dialog");
    modal.innerHTML = `
        <form method="dialog">
            <p>Hello!</p>
            <button>OK</button>
        </form>
    `;
    document.body.appendChild(modal);
    modal.showModal();
}
showCustomAlert();

The modification to the manifest came up with the same error as before. Whilst the showCustomAlert - did nothing. Double click the script and no response - presumably it compile and ran ok, but didn't add anything to the screen alertwise.
