Play bar without the drag/slider option

I'm working on a project that contains a few videos. The client wants the playbar for the videos, but without the scrubbing option. As there is no such functionality in Captivate 2019, I used a code (given below) that I found online. For the shorter videos, this code is successful in disabling the scrub feature. However for the longer videos, the scrubbing suddenly pops up in the middle of the video.

Is there any other way to disable the scrub feature?

// hide the slider thumbnail
var thumbEl=document.getElementsByClassName('playbarSliderThumb')[0]
thumbEl.style.display='none'
// disable drag and click slider navigation
if (!cp.playbar.mainMovie._jumpToFrame) {
cp.playbar.mainMovie._jumpToFrame =
cp.playbar.mainMovie.jumpToFrame
cp.playbar.mainMovie.jumpToFrame = function(a) {
var stack = new Error().stack
var callerIsNotPlaybar =
stack.indexOf('HTMLCanvasElement.moveSlider') == -1
&& stack.indexOf('PlayBarSlider.moveSlider') == -1
if (callerIsNotPlaybar)
cp.playbar.mainMovie._jumpToFrame.call(cp.playbar.mainMovie, a)
}
}
