Ability to update OpenGraph data (link preview) to shared prototypes
The default link text that appears when I share a prototype doesn't look very professional, nor is it very useful for people who see multiple of these in a day.
My suggestion is that you give us a place to put "About" data for the file, and that this is used as the OpenGraph text for link previewing in applications like Slack, Skype, etc.
I'm attaching a photo of what my current link share looks like, and what I propose could happen with some sort of "Info" text.
Note the current text (helpful for people searching) is "A prototype made with Adobe XD".
