Qt for Python (PySide/Shiboken)

Is there a guide for the vscode plugin for qml? Do I need to install Qt itself separately? Currently I use PySide6 and it doesn't work, saying Failed to import QtQuick.Layouts. Are your import paths set up properly? Did you set the "QT_QML_GENERATE_QMLLS_INI" CMake variable on your project to "ON"? [import]
