add web share api button

[ghost]

ndiego, let's sit here and talk about the web share api that now exists.
Wow, a single button entitled "Share" enables the system to open the native popover to handle the sharing. Very easy.
This is good to share content directly to apps installed on the system.

So please add a button in your plugin to achieve this, something like a "System Share button", so we can add it with your plugin. It is going to serve well alongside with the current sharing buttons that straightforward share content to other websites and services.

This plugin handles the web share api: https://wordpress.org/plugins/universal-web-share/

But I believe this is also a subject to your social sharing block. Yes. Please allow to insert this button with block supports like color, typography, prefix and suffix, as it is currently done. This is the downside of the Universal Web Share plugin.
