I've got 10 modules with C++ classes registered with QML_ELEMENT (sometimes with QML_SINGLETON).

• Modules are created with qt_add_qml_module.
• Source for modules are in src/<actions|devices|store>.
• URI follow core.actions, core.devices, core.store, etc.
• OUTPUT_DIRECTORY follow "${CMAKE_BINARY_DIR}/core/actions".
• In CMakeLists.txt in root folder I specified

set(QML_IMPORT_PATH
    ${CMAKE_CURRENT_SOURCE_DIR}/qml
    ${CMAKE_CURRENT_SOURCE_DIR}/src
    CACHE STRING "" FORCE
)

• Added -DQT_QML_GENERATE_QMLLS_INI=ON to CMake for configuration
• At "${CMAKE_BINARY_DIR}/core/actions" there are
  • qmldir (with module, plugin, classname, typeinfo and prefer fields pointing to existing elements)
  • coreActions.qmltypes which contains entries for hpp files with provided properties, methods and signals.
• Line import core.actions Qt Creator doesn't highlight as faulty.
• Qt Creator Tools > QML/JS > Reset Code Model and Tools > C++ > Update Pottentialy State Clangd Index Entries called and Qt Creator restarted

Application compiles and works fine. In GammaRay in Resources panel there're URI for C++ modules with qmldir inside.
WHY Qt Creator fails to Follow symbol under cursor (F2) or Ctrl-[ for any C++ class used as property type? (PS: At first I couldn't even F2 on DeviceActions {} - but somehow it started working.)

import core.actions

Item {
    property DeviceActions devActions: DeviceActions {}
}

Follow up: In Jetbrains CLion and VS Code I can use QML Language Server to support code completion and suggestions.
Everything is as above. Jump to QML components sources works fine. Jump to C++ classes source fails.
How can I help QMLLS to provide needed configurations or parameters?
