I want to use spine in multiple scenes

Hi. I want to use spine in multiple scenes.

I checked the example on the official example site.

https://labs.phaser.io/edit.html?src=src\spine4\spine%20parallel%20scene%20test.js

It is possible to use them in parallel like this.

however

https://labs.phaser.io/view.html?src=src\spine4\spine%20preloader%20test.js

With this test

https://labs.phaser.io/view.html?src=src\spine4\spine%20scene%20test.js

This test example did not work properly.

Should I use it in parallel?
Please answer

In these you can make it work with something like

function init () {
  this.plugins.installScenePlugin('SpinePlugin', SpinePlugin, 'SpinePlugin', this, true);
}

But I think it would be easier to avoid that. Load the Spine Plugin in a <script> instead and add it to the game.
