Property 'rexUI' does not exist on type [Scene]

[xpluscal]

I have the following code in

//game.ts
import 'phaser'
import RexUIPlugin from 'phaser3-rex-plugins/templates/ui/ui-plugin.js';

const config = {
...
  plugins: {
      scene: [{
          key: 'rexUI',
          plugin: RexUIPlugin,
          mapping: 'rexUI'
      },
    ]
  }
...

//MyScene.ts
import RexUIPlugin from 'phaser3-rex-plugins/templates/ui/ui-plugin.js';
...
export default class MyScene extends Phaser.Scene {
  constructor() {
    super(sceneConfig)
  }

  preload(){
    this.load.plugin('rexUI', RexUIPlugin, true);
  }

And I'm getting the error Property 'rexUI' does not exist on type 'MyScene'

What am I doing wrong here? Thx!
