Makie: What is a scene?

Could not answer the question after reading What is a Scene ?

Who can explain in simple terms where scenes fit in a mental picture of Makie?

The manual puts them close to a container, the code below suggests them being a property of axes:

f = Figure()                   
a = Axis(f[1, 1])                  
p = lines!(a, 0:0.1:10, cos))
...
if ispressed(a.scene, Mouse.left)

Confused.

The axis just has a scene in which the plots are drawn, it’s a low level container with plots inside and a projection or camera setting
