Access texture from another file

Hi all, I have created a Canvas texture in file a.ts:
this.textures1 = this.textures.createCanvas(‘canvastextures1’, 490, 180)
and now, I am trying call this.textures1.getContext() in file b.ts. How can I access this texture? Thank you.

If you’re in a scene, it’s

this.textures.exists('canvastextures1') ? this.textures.get('canvastextures1') : null;
