Can't use int variable in button textbox

[tEdward]

So, I'm trying to make an app in which if I push a button, the number on it will increase by one. I tried doing it by declaring a universal int variable(Num), and onClicked: Num++;. But I found no way to display that variable in text:...
I don't have the faintest idea how to do it.

Any help would be appreciated!

Thought I'd just post this as well

Button {
        id: button
        x: 110
        y: 220
        width: 375
        height: 180
        text: 
        font.pointSize: 30
        scale: 0.4
        anchors.verticalCenter: parent.verticalCenter
        anchors.horizontalCenter: parent.horizontalCenter
        onClicked: Num++;
    }

Also the button is from QtQuick - Controls 2.

@tEdward hi

Window {
    width: 800
    height: 600
    visible: true
    
    property int num : 0

    Button {
            id: button
            text: num //<
            onClicked: num++
        }
}
