Ability for Widgets to communicate between Users

I can broadcast data in a widget by using:
 

miro.broadcastData({
        value: 111
    })

I can receive this data by using:
 

miro.addListener('DATA_BROADCASTED', e => {
 console.log(e);
 alert("weeeeeeeeeee!");
});

If we could send data to the same widget on the same board for other users in a similar way, then this would open a lot of new possibilities to develop collaboration tools for the marketplace.

At the moment I can’t find any way to let my widget communicate between users.
