Native share from and to pwa

[raffis]

Is your feature request related to a problem? Please describe

No.

Describe the solution you'd like

I would like to see the possibility to share files from the webapp using the native share dialog.
Also I'd like to share files from other apps to the pwa.

• Share files from pwa using the native share dialog
• Share files to pwa using the native share dialog
• Share sharelink as text using the native share dialog
• Share permalink as text using the native share dialog

Describe alternatives you've considered

Currently the only option is to download the file and share it afterwards if possible.
