Not working on 8.9
Client side error : (TypeError) : navigator.clipboard is undefined

This may not be a problem of the addon or even Vaadin itself.
In modern browsers the “navigator.clipboard” object is only available for connections to localhost and for connections using HTTPS.
Using HTTP to any host other than localhost will cause the object to be undefined.
