Wave Command to Display Dynamic List of Active Users

[SevanBadal]

Issue

There is no way to tell when other users are active on the application

Solution

Create a command that broadcasts their presence on the application.

• A command named wave that runs until the user terminates it via :quit
• This terminal window can be left open in the background
• When other users start waving, a synchronized state is spread to all "waving" users via Supabase's presense api.
• OS notifications are pushed when a new user joins via node-notifier

Additional Information

There is an issue with the icon displaying in the native notification UI. node-notifier allows you to specify an absolute path to an image like this:

        nodeNotifier.notify({
          title: "New users have entered 📦",
          message: newUsers.join(', '),
          icon: '/absolute/path/to/image.png'
          sound: true
        });

However, I haven't gotten it to work on Mac. My issue is similar to this one: mikaelbr/node-notifier#71
