Hi, I have a Kotlin `ByteArray` that contains the binary data of an image (`image/png`).
I'm trying to display that image to the user.
So far I have:
```val blob = Blob(arrayOf(data), BlobPropertyBag(
    type = "image/png",
))
val url = URL.createObjectURL(blob)
window.open(url, target = "_blank", features = "noopener,noreferrer")```
However, running the code opens a tab with a small grey square, no matter the original image. I _think_ the blob conversion is the culprit, but I'm honestly not sure. Because `Blob` takes an `Array&lt;dynamic&gt;` , I have no meaningful way of knowing what's wrong with it.

I'm trying to display the file to the user, i might want to display a thumbnail as well, but yeah it won't go much further than that
