Inspect.exe is not identifying the UI elements of my QT application

I have been trying to access the UI elements of my QT application using inspect.exe. But unable to do so..

UI of my application is made in 2 ways:

1. qml
2. QWidgets

Whole UI of my application was not visible to inspect tool in the first place but I made the qml part visible by adding the three properties mentioned below

Accessible.name: "buttonSignIn"
Accessible.description: "Sign in button"
Accessible.role: "Button"

But don't know what to do with QWidget part.

Adding a link to the screenshot of my inspect tool below. Image
