How to use qt_generate_deploy_qml_app_script?

I am trying to deploy a Qt Quick application using Qt 6.8 for desktop with the following CMakeLists.txt configuration

cmake_minimum_required(VERSION 3.16)

project(DataLogStream VERSION 0.1 LANGUAGES CXX)

set(CMAKE_CXX_STANDARD_REQUIRED ON)

find_package(Qt6 REQUIRED COMPONENTS Quick SerialPort Graphs Qml)

qt_standard_project_setup(REQUIRES 6.5)

qt_add_executable(appDataLogStream
    main.cpp
)

qt_add_qml_module(appDataLogStream
    URI DataLogStream
    VERSION 1.0
    QML_FILES
        Main.qml
        QML_FILES
            PortSelection.qml
            PlotStream.qml
        SOURCES
            portselectionservice.h portselectionservice.cpp
            plotstreamservice.h plotstreamservice.cpp
        RESOURCES
            refresh-icon.svg
)

qt_add_resources(appDataLogStream "config"
    URI DataLogStream
    FILES
        qtquickcontrols2.conf
)

qt_add_resources(appDataLogStream "images"
    URI DataLogStream
    FILES
        logo.png
)

# Qt for iOS sets MACOSX_BUNDLE_GUI_IDENTIFIER automatically since Qt 6.1.
# If you are developing for iOS or macOS you should consider setting an
# explicit, fixed bundle identifier manually though.
set_target_properties(appDataLogStream PROPERTIES
#    MACOSX_BUNDLE_GUI_IDENTIFIER com.example.appDataLogStream
    MACOSX_BUNDLE_BUNDLE_VERSION ${PROJECT_VERSION}
    MACOSX_BUNDLE_SHORT_VERSION_STRING ${PROJECT_VERSION_MAJOR}.${PROJECT_VERSION_MINOR}
    MACOSX_BUNDLE TRUE
    WIN32_EXECUTABLE TRUE
)

target_link_libraries(appDataLogStream PRIVATE
    Qt6::Quick
    Qt6::SerialPort
    Qt6::Graphs
    Qt6::Qml
)

include(GNUInstallDirs)
install(TARGETS appDataLogStream
    BUNDLE DESTINATION .
    LIBRARY DESTINATION ${CMAKE_INSTALL_LIBDIR}
    RUNTIME DESTINATION ${CMAKE_INSTALL_BINDIR}
)

qt_generate_deploy_qml_app_script(
    TARGET appDataLogStream
    OUTPUT_SCRIPT deploy_script
    NO_UNSUPPORTED_PLATFORM_ERROR
)

message("deploy script name: ${deploy_script}")
message("qt_deploy_support: ${QT_DEPLOY_SUPPORT}")
install(SCRIPT ${deploy_script})

It creates a QtDeploySupport.cmake file with this, but when I try to run the application in debug (same in release) I get following error:

14:52:22: Process failed: The program "appman-controller.exe" does not exist or is not executable.
14:52:22: Deploy step failed.
14:52:22: Error while building/deploying project DataLogStream (kit: Desktop Qt 6.8.2 MSVC2022 64bit)
14:52:22: When executing step "Install Application Manager package"

I am not sure what I am missing, I have already installed Qt Installer Framework. Do I need to install anything else?

It seems to be working now, I had to change appDataLogStream to DataLogStream and I am able to run it. Not sure why though. But I still don't understand how to use qt_generate_deploy_qml_app_script? What should I do with the generated script?
