Start the screen cast session. This will typically result the portal presenting
        a dialog letting the user do the selection set up by SelectSources.

              node ID (the first element in the tuple, and a Vardict of
              properties.

The array will contain a single stream if 'multiple' (see
              SelectSources) was set to 'false', or at least one stream if
              'multiple' was set to 'true' as part of the SelectSources method.
