Cannot apply transitions when using StateGroup in QML

[jay1]

I am trying to use the states in the QML but when i try to add the StateGroup the transitions are not applied or not visible but the state changes.

The example i tested used to file "Main.qml" and "CustomComponent.qml".
The "Main.qml" contains the customcomponent and button. when a button is pressed the state of the customcomponent is changed.
The states are defined in the "CustomComponent.qml" file.

Am I using the QStateGroup Tag in "CustomComponent.qml" in wrong way ?
Can someone kindly suggest the correct or standard way ?

Main.qml

// ------------------------------File: Main.qml------------------------------------------------
import QtQuick 2.14
import QtQuick.Controls 2.14
import QtQuick.Window 2.14

Window {
    visible: true
    width: 640
    height: 480
    title: qsTr("Test Sample")

    CustomComponent
    {
        id: customComp
        width: 50
        height: 50
        x: 50
        y: 50
    }

    Button
    {
        id: button
        width: 150
        height: 150
        x: parent.width/2
        y: 150
        onClicked:
        {
            if(customComp.m_status === 'HIDE')
            {
                button.text = 'SHOW';
                customComp.m_status = 'SHOW';
            }
            else
            {
                button.text = 'HIDE';
                customComp.m_status = 'HIDE';
            }
        }
    }
}
