Control Ableton Link via LOM

Hi everyone,

I need to control Ableton Link toggle via Max For Live for a multimedia system I'm designing.
The LOM documentation states "is_ableton_link_enabled" as a property of "Song", with methods to set, get and observe.
I tried a in any way I could find to assemble a prototype to get/set that feature, via live.property, live.function, live.object, live.observer with help via live.path but seems they cannot access that property.
In the end, everyone of those do print out on console something like: "'Song' object has no attribute 'is_ableton_link_enabled'".

Here's an example patch

I don't know if it's a bug or I am making silly mistakes, call me out if you find anything wrong.

I'm on Win10 LTSC, Ableton Live 11.0.12, Max 8.2.0.
A friend on mine tried it out with same results on OSX, don't know his Live/Max versions though.

Checking the LOM documentation further, I found "This document refers to Ableton Live version 11.1", which is not release yet, as far as I know. Maybe this could be one of next Live version added features?
