Is there any example to change animation using Phaser 3 with Spine?

Hello
Is there any simple example to change animation using Phaser 3 with Spine?
I am beginner of spine and I do not have any example about change animation using Phaser 3 with Spine.

I try to use the following example to edit
https://labs.phaser.io/edit.html?src=src/spine/basic%20spineboy.js&v=3.60.0-beta.21

and add this code

 var boy = this.add.spine(400, 600, 'set1.spineboy', 'idle', true);
 boy.setMix('idle','walk',1);

but not work for me, any idea???
Thank you very much

please use
boy.play('walk', true);
instead of
boy.setMix('idle','walk',1);
