You can re-use the call object multiple times (a sequence of
join(), etc method calls will work fine).
But when you are finished with the
daily-js call object, you should call
destroy() to free all resources associated with it.
This is particularly important if you plan to create another
daily-js object in the future. If you don't call
destroy(), and later create a new
daily-js call object, the event listeners from the old object and the new object will interfere with one another.
