Is there a way to add custom meta data back to entry after the upload?

```elixir
import { UploadClient } from '@uploadcare/upload-client'

const client = new UploadClient({ publicKey: "publicKey" })

const Uploadcare = (entries, onViewError) => {
    const uploadEntry = makeEntryUploader(onViewError)
    entries.forEach(uploadEntry)
}

const makeEntryUploader = (onViewError) => async (entry) => {
    const onProgress = ({ isComputable, value }) => {
        if (isComputable) {
            let percent = Math.round(value * 100)
            if (percent < 100) { entry.progress(percent) }
        }
    }

    const abortController = new AbortController()
    onViewError(() => abortController.abort())
    const result = await client.uploadFile(entry.file, {
        onProgress,
        signal: abortController.signal,
    })

    // How to add the data to the entry?
    entry.meta = {
        ...entry.meta,
        // This doesn't work:
        uploadcare: result
    }
    entry.progress(100)
}

const uploaders = {
    Uploadcare,
}

export default uploaders

```

I have this in the live view:

```elixir
defp presign_upload(entry, socket) do
    meta = %{uploader: "Uploadcare"}
    {:ok, meta, socket}
end

```

But I only get the url and stuff in the response from the `await client.uploadFile(entry.file, {`

Has anyone ran into this? Do I need move the uploading to the server side to get the required data?

For anyone else interested this is the current solution i arrived at.  
It’s a hack with the least amount of indirection that i could come up with.
