Add a Speaker (Sound ON/OFF) Button for YouTube embedded Video on a Wordpress Site (Avada Theme)

For our embedded video we need a button on the start page where you can switch the sound on and off. Unfortunately, at the moment you can only set the video to with or without sound. It is embedded on YouTube. It should be that you go to the website, then the video starts and a crossed out speaker should appear, which just symbolizes that the sound is off. If you then click this, the strikethrough line goes away and you can only see the loudspeaker and hear the sound. So you should be able to easily switch the sound on / off from the video. The website is on Wordpress, the video is embedded via YouTube and the theme is Avada for Wordpress. It is important that the video is embedded exactly like this. So full screen and it must not be cut off at the bottom, side or top. Say responsive is also very important.
