QQuickWebEngineProfile warning advising to use WebEngineProfilePrototype

[lucytronad]

Hello,

I use a QML WebEngineView for which I set a profile created in C++ so that I can customize its URL request interceptor using the method QQuickWebEngineProfile::setUrlRequestInterceptor().

However since I upgraded to Qt 6.9.0 I have the following QML warning:
15:32:46.766|WARNING|:-1||<Unknown File>: QML QQuickWebEngineProfile: Please use WebEngineProfilePrototype for profile creation from 6.9, as this function will be deprecated in the future releases
I did not get how to accomplish the customization of the request interceptor using WebEngineProfilePrototype to create the profile on the QML side.

Can you help me ?

Thanks,
Lucie
