Qt creator design tab doesn't link to ressource file in Qt for Python project

I created a Qt for Python project. I made a resources file and a ui which both are on the project tree. From the design tab, if I want to set a property of any QWidget to link to a file in the resource file, the resource file doesn't exist in the pop-up window. On Qt Designer, to resource pop-up have a "open existing resource file" button. I would expect that on Qt Creator, since files are in a project, it would link it automatically
