Deprecated method createjs.Ticker.setFPS(24);

Hello, 

I am attempting to change the frame rate during certain sections of an Adobe Animate HTML5 Canvas project.

createjs.Ticker.setFPS(24);

In the past, I was able to temporarily change the fps using the above code, however I get an error now that this method is deprecated. Can someone please direct me to infromation/examples about how to change the fps from within a canvas project.  I see this documentation:

https://createjs.com/docs/easeljs/classes/Ticker.html#property_interval

however I do not completely understand how to apply it.

I am trying the following without success:

Ticker.framerate = 24;

Thank you in advance...
