Access Root File url with AWS keys

[klobassimon]

Does anyone know if there a way to access the root URL of a private file with the AWS access keys and use this in a workflow, dynamically?

An example of which I have pasted below with some xxx for privacy.

URL I need:
https://2623b27bf95a3fe96exxxxxxxxxxxx.cdn.bubble.io/f1692924249998xxxxxxxxxxx/Test%20Adobe%20sign.pdf?AWSAccessKeyId=xxxxxxxxxxxxx&Expires=xxxxxxxxxxxxxx&Signature=xxxxxxxxxxxxxxxxx
