ImagePicker - image to blob

How to / Third Party Tooling

import * as ImagePicker from ‘expo-image-picker’;
let result = await ImagePicker.launchImageLibraryAsync({
mediaTypes: ImagePicker.MediaTypeOptions.Images,
base64: true,
quality: 0
});```

How can I change this to blob format to send it to an api?
here is what I tried

const response = await fetch(result.uri);
const blob = await response.blob();
return console.log(JSON.stringify(blob));

{“_data”:{“name”:“2909c97e-d7ca-4d33-9f8c-5a83a534d270.png”,“size”:114765,“offset”:0,“type”:“image/png”,“lastModified”:0,“blobId”:“38f9cbd1-1f59-4176-9ca7-a84ae2e0a80f”,“__collector”:{}}}```

I am unsure what to do next, thank you in advance!
