FlyViewToolStripActionList.qml adding new tool

image
Hello, I am very new to qgc. I added an icon to the toolstrip above and I want it to open a menu when I press this button. I also created my qml file for this, but can you help me with how I can open my sample qml file without losing the main screen?
ToolStripAction {
text: qsTr(“example”)
iconSource: menuVisible ? “/InstrumentValueIcons/close.svg” : “/InstrumentValueIcons/menu.svg”

        // enabled: QGroundControl.multiVehicleManager.activeVehicle
       onTriggered:
    }
