Select multiple groups with mouse drag in draw.io

When having multiple elements in draw.io, I like to group them. Then, when having multiple groups, I’d like to select them by click-dragging a selection box over them. But by doing so, every single element is selected, but not the group itself.

The only workaround I found so far is by Ctrl-clicking every single group.

Is there anypossibility to select groups by click-dragging a selection box over them?
