Does anyone know how we can get files (attachments) from our Streak Box into Airtable?

We use Streak for our daily CRM, but use Zap to create records of concrete leads in Airtable.  We attach files to the box in Streak and want those files in Airtable as well.  We can send the file key, but that doesn’t give us the actual file (or link to a file) in Airtable.
