Hello,
Currently we are uploading a document to our opportunity. I need a way automate generating a public share link of a file and setting this to it's related opportunity url field. 

the idea is this will then be referenced later in a email template.

at the moment we have to:

1. upload the file

2. click on the file which navigates away from the opportunity

3. generate the share link

4. copy the link

5. return to the opp and paste this into the url.

any help would be appreaciated.

Cheers
Phill
