This forum is for issues that are code related on your site.
You are asking about the Wix File Share app which has it’s own Wix Support pages and is not connected with Wix Corvid.

If you are wanting more help with the Wix Editor itself or any of Wix apps, then you are better suited going through Wix Support instead.
