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

In the script below, I'm lazyloading two videos. My script is designed to remove the overlay image from the selected video when clicked. However, it's also removing the overlay image from the second video and placing it above it. Another click removes the duplicate image, and a third click plays the video.

How do I remove only the image for the selected video in a way that doesn't affect a second video on the page?

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();
      }
    });
  });
});
