Uploading a File to Baserow Table into a File Field

I like to upload a file via a Make.com automation into a Baserow Table, into a file field so the uploaded image shows as a Thumbnail. How to do this.

I tried the following already:

=> This doesn’t work, the API request always results in “detail”:“Authentication credentials were not provided.”

=> this also does not work and also I need a detailed step by step guide how to make the file upload automation in Baserow work

There are also other Baserow modules like Upload a File and Make API Call where I cannot find any documentation anywhere how these work exactly. Please provide an update step by step guide which is checked that this really works. Thank you.
