Impossible to access(display) the image url from Strapi v4 with ReactJS

This is how I was able to get the images:

  const evtImages = evt.image.data;

  const newImg = evtImages.map((img) => {
    return img.attributes.formats.thumbnail.url;
  });

  const imgString = newImg.toString();

I then passed imgString to my JSX:

<Image
          src={evt.image ? imgString : "/images/event-default.png"}
          width={170}
          height={100}
        />

I know that’s a lot of typing but It worked fine.
