How to load asset from zip file?

Question

How can I load an asset (model, texture, etc.) from a .zip file in Python's Ursina module without extracting it?

I tested this code:

from ursina import *
app = Ursina()
x = Entity(model="cube", texture="assets.zip/texture.png")
p = EditorCamera()
app.run()

But with no success (warning in the command prompt + entity appears white):

warning: missing texture: 'assets.zip/texture.png'

My file/folder structure is like this:

<root>/
  test.py
  assets.zip/
    texture.png
