I’d love to see social media sharing buttons or something that would allow users to share images and products. That would ROCK. 
you can, just make a button and then set the action to open the share sheet.
Problem with the share sheet button is that it only shares a URL to image - so for example, not possible for users to share an image to instagram.
I build for others and this is requested constantly
