Once you have imported a document into the platform, a URL link is automatically associated with this file. This link allows you to download/display the document when you click on it.
To find the URL of one of your documents hosted on the platform:
Go to "Event Data Documents" and click on the document of your choice
A link appears under the "Document" field, you can easily copy and reuse it!
The URL of a document can be useful if you want to make it available from the home screen, behind an "External Link" button. See: How to create a button?
