How can I get Webstorm to recognize Angular assets folder

I have a fairly classic Angular 19 project setup (at least I think its fairly classic).

In my angular.json I declare the assets as follows:

"assets": [
  {
    "glob": "**/*",
    "input": "src/assets/",
    "output": "/public/"
  }

But when I do that Webstorm doesn't recognize the /public/ folder. And so all the references to assets in my code have warnings indicating “cannot resolve directory public”.
Is there an easy way to resolve this?
