Origin for Container

According to Phaser 3 Docs (Phaser 3 API Documentation - Class: Container)

The origin of a Container is 0x0 (in local space) and that cannot be changed
But created container has 0.5 0.5 origin values:

const cont = scene.add.container();
console.log(cont.originX, cont.originY); // display 0.5 0.5

Why?

They’re two different concepts. (0, 0) is the local position that Container children are transformed around.

How I can change an external container origin to 0,0 ?

What are you trying to do overall?
