How do you enable exifInfo on attachments?

Good Day

I'm trying to figure out how to view the exifInfo data after I fetch the attachments from ArcGIS JavaScript. I added attachments to the feature and I know road1 and road5 have exif data:

When I fetch the data I get this object back:

How do I enable the exifInfo? I was reading about a flag that I have to turn on in the settings of the feature layer but I can't see or find any option for this.

Thanks

Setting returnMetadata: true in the query doesn't work and I can't find the setting in the feature service settings.

Solution: Don't use the getAttachments function from the library, if you build the URL for the query, including returnMetadata, and use a plain httpGet, you'll have success.

I ended up using this function to grab the attachments, and they came with their EXIF Data:

const objectQuery = '?objectIds=' + result.features[0].attributes.FID;
const json = '&f=json';
const returnMeta = '&returnMetadata=true';
const token = '&token=' + this._session.token;
const attachmentUrl = this.attachmentURL + 'queryAttachments' + objectQuery + token + returnMeta + json;

// TODO: Place a proper type reference here
this.http.httpNoHeader(attachmentUrl).then((attachmentRes: any) => {
  console.log('Manual Attachment Query');
  console.log(attachmentRes);
}).catch((error) => {
  console.log('Error');
  console.log(error);
});
