"Download", "Edit Metadata" and "Access" buttons should perform different actions

Steps to reproduce:

• Set up Salesforce using ngrok and by following the documentation.
• Create an opportunity in Salesforce and verify that it has created a workspace in Nuxeo.
• Create several different documents in Nuxeo and verify that they are visible from the Salesforce Opportunity iFrame.
• From the iFrame, on each document, you should see the following icons: Full Preview, Download, Edit Metadata and Access.
• Click on the Download icon.
  => A browser tab opens to the document in Nuxeo (Web UI).
• Click on the Access icon.
  => A browser tab opens to the document in Nuxeo (Web UI).
• Close the tab.
• Click on the Edit Metadata icon.
  => A browser tab opens to the document in Nuxeo (Web UI).
  => In order to edit the document, I still have to click on the Edit icon from within Nuxeo.

Expected behavior
One of the following:

• Clicking the Download icon should provide a direct download of the document
• Clicking the Edit Metadata icon should allow me to edit the document from within the iFrame, OR
• Clicking the Edit Metadata icon should open the Edit Metadata form directly in Nuxeo, OR
• There should be no Edit Metadata icon, I can just click the Access icon, then Edit instead.
