Download attachment from airtable

I am mapping an airtable data to a list in softr. When an item is clicked I want to download the file. I selected “on item click” → action: open url → from the drop down I picked the column “attachments” which holds the attachment file in air table. When I open the list in preview and click on the item the link is invalid format. It is prefixed with `https://FILE_NAME (air_table_valid_attachment_url)
how to I remove the prefix and the closing parenthesis at the end?

What if you map into a file type field vs action button ?

this works but it’s not ideal. It shows the full file name. I would prefer a link “Download” or a button “Download”. Any idea how to do that?
