Mysql e Report Viewer - Mysql não aparece em "Escolher Fonte de Dados"

Eu uso o Visual Studio Community 2017, Mysql for windows 2.0.5, Mysql Conector/NET 6.9.12 e outras versões destes dois. Mas não consegui fazer a conexão com o banco de dados no Report Viewer fazer o Mysql aparecer no "Escolher Fonte de Dados".

O meu app.config está configurado assim:
