Remove playback speed control in interactive videos

Hi, I'm just wondering if there is a way to remove the ability to change the playback speed of an interactive video. I've been having issues with students putting the video on at 2x, and I'm trying to find a way to prevent that.

Hi,

 

The easiest way is to use a PHP hook, to add your own CSS-file to the content type. Please visit the Visual Changes page for more details.

I've tried adding this to the custom CSS section of my installed moodle theme, and it doesn't seem to be working. Am I on the right track? Telling me to just use CSS isn't really helpful, as I know pretty much nothing about CSS...

.h5p-control.h5p-playbackRate {

  display: none;

 

}
