UPDATE: Prompt a dialog when clicking 'Share'

Note: this should address #304

To test it, please

• Ensure the URL is created properly
• Ensure the 'copy URL' button works properly
• Ensure it's visible on mobile (not the QR code, as it's hidden on mobile devices)

Awesome!
I deployed a version of this to try it out.
You will need to squash the commits and remove the WIP commit.
Let me know if you need help with that
