Solicita se o aplicativo precisa ser iniciado na inicialização da API
quando a guia já estiver sendo transmitida. Apps em conteúdo incorporado (como
iframes) precisam definir esse campo como CAST_THIS_TAB se não forem o app
principal da página. Esse valor também configura o comportamento padrão do
pop-up de extensão da página.
Função invocada quando a disponibilidade de um receptor do Cast compatível com o app em sessionRequest é conhecida ou muda. Essa função
sempre será invocada pelo menos uma vez após a conclusão da inicialização.
Listener invocado quando uma sessão é criada ou conectada pelo SDK.
Essa função pode ser invocada após a inicialização, se houver uma
sessão criada ou conectada automaticamente. O método requestSession não faz com que esse listener seja invocado, já que ele tem o próprio callback de sucesso.
