I have a lot of PDF file attachments in my records, and I would like to directly access and use the thumbnail images that Airtable generates for each PDF.
I can manually extract the thumbnail URL by right-click on an image preview image in my attachment field.
Is there an Airatble formula function that can expose these URLs so they can then be accessed by Zapier/Integromat or similar tools? - eg something analogous to what
RECORD_ID() does to expose the record ID?
