I have a canvas app that stores attachments related to an Entity in CDM. I also have a model driven app for back office processes related to that same entity. How can the model driven app get access to the attachments related to the entity? I can't seem to find a way to display, via a list or a form (for the entity), an attachment field. When using SharePoint to store attachments, you can add the Attachment field to the list. When you open a particular record, the attachment file name is displayed and can be downloaded. Is this same type of functionality available in a model driven app?
