An action block that awaits content shared/sent from within another app.
The fiber will pause until content has been shared, usually by a “share” button/menu, then choosing Automate flow is the target.
Set a content MIME type to limit the type of data shared with this fiber. The data shared is assigned either to the content URI, the content text or possibly both if the content is text.
The assigned content URI may not be a file, nor accessible by any other apps, use the Content copy block to extract the content to external storage.
