Communication between 2 different objects in 2 different QML files

Question

I have one main.qml file and I have other "example.qml" file. When I push a button from "example.qml" file I want to change a text in "main.qml" file. I tried defining the source of the text. I tried send signal. I tried using loader but always came to a dead end.

import QtQuick 2.12
import QtQuick.Layouts 1.12
import QtQuick.Controls 2.12
import QtQuick.Controls.Imagine 2.12
import QtQuick.Window 2.0

//main.qml
Window {
       visible: true
       width: 1080
       height: 720
       color: "black"
       title: qsTr("MY GUI")

    Text {
       id: deneme
       x: 100
       y: 400
       color: "white"
       text: "Trial"

   }
}

//example.qml

Item {
    id: difflock

    Rectangle{
        id: diffLockRect
        width: 1080
        height: 720
        color: "red"
        signal  mySignal

        Button{.


          onClicked: main.deneme.text = "Finally"
        }
    }
}

Create a new qml named by Example.qml(first letter should be capital)
Define in main.qml
Example.qml can access the objects in main.qml

main.qml

import QtQuick 2.12
import QtQuick.Layouts 1.12
import QtQuick.Controls 2.12
import QtQuick.Controls.Imagine 2.12
import QtQuick.Window 2.0
    Window {
           visible: true
           width: 1080
           height: 720
           color: "black"
           title: qsTr("MY GUI")

           Example{id:rfrnc} // You can also reach the other qml objects by using this id

        Text {
           id: deneme
           x: 100
           y: 400
           color: "white"
           text: "Trial"

       }
    }

Example.qml

import QtQuick 2.12
import QtQuick.Layouts 1.12
import QtQuick.Controls 2.12
import QtQuick.Controls.Imagine 2.12
import QtQuick.Window 2.0

Item {
    id: difflock

    Rectangle{
        id: diffLockRect
        width: 1080
        height: 720
        color: "red"
        signal  mySignal

        Button{

onClicked: deneme.text = "Finally"
        }
    }
}
