How can I @link in JSDoc to a method in a class returned by an IIFE?

Due to JS runtime constraints, I need to use an IIFE that returns a class. How can I use {@link } in JSDoc to link to methods in that class? The normal syntax Class.method doesn't work.

const Singleton = (function () {
  // IIFE
  return class {
    init() {
      console.log('Spreadsheet clears');
    }
  };
})();

class Foo {
  method() {
    console.log('Foo.method');
  }
}

class Bar {
  /**
   * See also {@link Foo.method} and {@link Singleton.init}  <-- how can I link to Singleton.init?
   * ^ Cmd/Ctrl+click on init doesn't go to the method above.
   */
  method() {
    console.log('Bar.method');
  }
