My team uses the annotations table to upload files and relate them to specific records in a table.

All I want to do is to lookup one of these records and attach the .pdf file to a Send Email (V2) action in power automate....
Just listing the record and adding it as an attachment does not work:
Add the base64 string to the "Send an Email (V2)" action

The result:
