RobotFramework 3.2.2 + eclipse + python3

I’ve installed and configurated eclipse + robotframework3.2.2 + python3 (3.11 orc1) but library “Dialogs” shows up not accessible. Anybody has any solutions?

When click on the Dialogs show up: Unable to open documentation for library ‘Dialogs’ from 'null

and this library " Diaglos" is on the Robot Standard libraries
