How to move pivot temporarily in just one axis?

Hello everyone! In documentation there is mentioned that moving pivot temporarily is available with middle mouse button (MMB). For example here: Transforming Actors in Unreal Engine | Unreal Engine 5.0 Documentation

“By holding down Alt and dragging with the middle mouse button, you can use the Translation Widget to move the pivot temporarily.” But when I hold down Alt, nothing really happens. I can move a pivot in the plane of a screen just by holding MMB on a pivot’s white dot and only that. But it isn’t practical for me, so am I doing something wrong with this Alt instruction? And is there a way to move pivot temporarily in just one axis?

I have found the answer here:

To move the pivot temporarily in just one axis you must hold MMB+LMB on it’s widget and move the cursor.
