Thanks for your help guys! I did my research and the final answer was matching the correct aria attributes and some html5.

<figure>
            <div class="video">
                <video id="main_video" controls >
                    <source src="<?php echo $source_video?>" type="<?php echo $video_source['mime_type']?>">
                    <source src="<?php echo $source_video_2; ?>" type="video/webm">
                </video>
            </div>

            <details >
                <summary aria-controls="transcript_content" tabindex="0" aria-expanded="false" id="show-hide-transcript" > Transcript </summary>
                <div id="transcript_content" aria-live="off" aria-atomic="true" aria-relevant="all" tabindex="0" aria-expanded="false" role="article"  ><?php echo $video_transcript ?></div>
            </details>
        </figure>
