Looking to create button(s) for playback speed - Slide Video from YouTube

Hello!

Working on a project in Captivate 2019 currently that I've imported a slide video from YouTube for a section, using Media > Video > Slide Video > insert URL from YouTube.

The video displays fine and plays in HTML5 preview. The video is a bit lenghty (6mins). I want to give learners an option to speed up 1.5x or even 2x. The YouTube video in the slide does not have any playback options in it. The playback bar in Captivate itself does not work either.

I've tried the javascript method using a variable and playback rate to create a button, but it does not work here.

var vid = $('video');

vid[0].playbackRate = 1.5;

Any thoughts or if this is possible? I just want the slide video to have some playback controls for speeds.

Hopefully its something simple I've overlooked.
