Mysql 8.3 InnoDB Cluster R/W spliting

[drivet1024]

Hi, I try to use MysqlConnector with my 8.3 innodb cluster. When you create a command with only SELECT it suppose to go to the first READ_ONLY node. In my case I try with SELECT @@hostname and it return me always the R/W node. When I try tha same thing with a Mysql Client software it return me node2 ou node3. DO ou know what exactly I'm doing wrong.
The R/W split is a nice feature.
