Querybuilder.js – How can I limit the conditions to have “AND” in the root, and “OR” in the subgroups?

I am used to working in C#, and just got handed this project with querybuilder.
I have been searching for hours and can’t seem to figure out how to achieve this.

What I want is for the root condition to be “AND” – which is default.
But since it is default – for every subquery (new group) I add, the default condition is “AND”, but I need it to be “OR”.

I added a photo which you can reach with below link.

Does anyone have an idea? It would be highly appreciated.
