Saving Arnold RenderView output images with python

[count.temp20]

Hello,
I've been stuck for hours trying to figure out how to save snapshots in the Arnold RenderView in maya using python. There documents for arnold's python command are almost none existent. The only helpful thing I found online was this. The image below shows exactly what I'm looking for. I believe it should be quite simple!  I did the same thing with V-ray and it was very straightforward. 
If anyone has a solution for this, please let me know. 
Thank you.

Hi,
I'm using the opportunity of this post to report having exactly the same issue, which is very frustrating when developing pipeline solutions for animation studios with Maya 2024 and Arnold.

Being able to render images from Python is one the most common processes managed in a 3D Pipeline, and not being able to do so because of a lack of online documentation is discouraging.

Could you please help us by improving the documentation regarding the Python API for Arnold rendering ?
This page for mel lacks details on what parameters can be given to functions (what can we give to -options of arnoldRender ?)
And this page could be enriched with the cmds details of arnoldRender() and arnoldRenderView().

Thanks a ton in advance.
