After checking out other posts on embedding videos that didn't help fix my issue, I seek some suggestion in making the video autoplay along with the audio as the page is visited. Below is the code embedded into my WordPress page here.
<iframe width="560" height="315" src="https://www.youtube.com/embed/ikTEJCk0Da0" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>
I did use query string like https://www.youtube.com/embed/ikTEJCk0Da0?autoplay=1 but it just makes the progress bar move but the video.
I did also use https://www.classynemesis.com/projects/ytembed/ to get the link, but it didn't help either.
