Engine.GetSimRate/SetSimRate from JS script

[CulturedCait]

Hi guys!

I'm working on a new script and I was wondering if there is a way to execute Engine.SetSimRate / Engine.GetSimRate from JS trigger script? It works if executed directly from the console, but using these functions inside JS produces following error:

ERROR: Error in timer on entity 1, IID103, function DoAction: TypeError: Engine.SetSimRate is not a function

This is my test trigger:

Trigger.prototype.TestDelay = () => {
	Engine.SetSimRate(20);
}

const trg = Engine.QueryInterface(SYSTEM_ENTITY, IID_Trigger);
trg.DoAfterDelay(5000,"TestDelay", {enabled: true});

I'm on release-a27.1 6a576.

Do you have an idea how to change simulation speed from within javascript? Is it even possible using trigger mechanics?

Thank you.
