How to remove the overlay image on only the selected lazyloaded video?

const getVideoId = (wistia_vid) => {
  const classes = Array.from(wistia_vid.querySelector(".wistia_embed").classList);
  const idClass = classes.find((cls) => cls.startsWith("wistia_async_"));
  const id = idClass.replace("wistia_async_", "");

  return id;
};

const removeElems = (wistia_vid) => {
  const toRemove = Array.from(
    wistia_vid.querySelectorAll(".wistia__overlay, .embed-youtube__play, .embed-video__play")
  );

  toRemove.forEach((node) => node.remove());
};

Array.from(document.querySelectorAll(".wistia")).forEach((node) => {
  node.addEventListener("click", () => {
    const videoId = getVideoId(node);
    let wistiaSupportScripts = [
      //adds jsonp file to provide security over requests
      `https://fast.wistia.com/embed/medias/${videoId}.jsonp`
    ];

    removeElems(node);
    
    //Checks if above scripts are already loaded, and if they are... they won't be loaded again
    const id = 'script-ev1';
    if (!document.getElementById(id)) {
      // const id = 'script-ev1';
      var script = document.createElement('script');
      script.id = id;
      script.onload = () => {
        console.log('Ev-1.js loaded and ready to go!');
      };
      script.src = `https://fast.wistia.com/assets/external/E-v1.js` ;
      document.getElementsByTagName('head')[0].appendChild(script);
    } else {
      console.log(`Ev-1.js script with id: ${videoId} already loaded.`);
    }     
    
    //loads supporting scripts into head
    for (var i = 0; i < wistiaSupportScripts.length; i++) {
      let wistiaSupportScript = document.createElement("script");
      wistiaSupportScript.src = wistiaSupportScripts[i];
      let complete = false;
      if (
        !complete &&
        (!this.readyState ||
          this.readyState == "loaded" ||
          this.readyState == "complete")
      ) {
        complete = true;
        console.log(`JSONP script was added.`);
      }

      let wistiaContainers = document.querySelector(".wistia");

      wistiaContainers ? document.getElementsByTagName("head")[0].appendChild(wistiaSupportScript) : console.log("No Wistia videos here.");
    }     

    window._wq = window._wq || [];
    _wq.push({
      //globally scoped
      id: videoId,
      options: {
        autoPlay: true,
        volume: 0.5
      },

      onReady: function (video) {
        playedOnce = true;
        video.popover.show();
        video.play();
      }
    });
  });
});
