[Interest] best base style for dual Qt5/Qt6 QML app

[Александр Иваш]

I need to support Qt5 & Qt6 builds of the same desktop QML
application. Everything works already except QML components styling.
The issue is that the original Qt5 application was based on 'Material'
style, which dramatically changed in Qt6.

Question 1: Is there any way to make Qt6 'Material' look like Qt5 one
(or vice versa)?
Question 2: If not, what is the best candidate for base style for
creating cross-platform UI which would look the same on all the
desktop platforms in both Qt 5 and Qt 6?
