How to find the total views of all videos in a YouTube PlayList?

I am trying to find the total number of views of all videos in a playlist I own in YouTube. I can see that a "total views" number is posted under the playlist name. However this appears to be the number of views generated by entering the playlist first. When I add up the number of views of individual videos I get a substantially larger number because, I assume, most of videos are watched by following a link other than the playlist.

In particular using the following JS in the YT console

ytInitialData.header.playlistHeaderRenderer.viewCountText.simpleText

just gives the same number that is available under the playlist name.

ChatGPT gives the following JS

var totalViews = 0;var videos = document.querySelectorAll('ytd-playlist-video-renderer');for (var i = 0; i < videos.length; i++) {  var viewsElement = videos[i].querySelector('#metadata > span:nth- child(1)');  if (viewsElement !== null) {     var views = viewsElement.textContent.trim().replace(/\D/g,'');     totalViews += parseInt(views);  } } console.log('Total views of all videos in the playlist: '+ totalViews);

But this gives a total count of 0.

Could it be that the count the not available in the HTML source code? And how do we get the total count?
