Prevent seeking (fast forward) via JS as toggle switch in theme config or embed popup

Example and info:

Also see here:

I have added the js into the custom/advanced but cannot get it to work properly.

There are probably more folks like me, which would benefit from a simple toggle switch when embedding a video.

Bonus:

-adding fields for start time and end time of the video. this already works well and easy when adding myvideo.mp4#t=125,185 to the src=

Why? my video might be 30-60min long. Relevant are a few min here, there and there.

I can embed the video without post editing, cutting trimming and rendering, so I save a lot of time! This also keeps the media library small, since only one video file is stored and not the raw original plus post edited sections of the original.

Problems:

-The customer should not be able to fast forward the training section!!

-customer should only be able to access the defines section of the video, as there could be sensitive information in other parts of the video. (when adding myvideo.mp4#t=125,185 to the src= the video will start and stop as expected, but the user can then freely use the seeking slider to browse the entire length of the video)

-the customer could download the video and access sensitive information (this can be prevented by:

<video

id="video"

controls="controls"

preload="none"

controlslist="nodownload"

oncontextmenu="return false"

>

<source
