Vimeo Background Video with Play Sound Toggle

From my Webflow online course community came the wish to build this video player, which basically runs in a loop without sound as a background video. If you click on on the unmute button, the video plays from the beginning and the sound is activated.   We need a bit of custom jQuery code for this. In addition, the Vimeo API must be included if you want to address Vimeo iFrames. Watch the tutorial here: https://youtu.be/mKFZxHpYGng
