Aligning grouped objects (3d scan mesh) with the gumball in Rhino 8

Hi Group

I have imported 3d mesh scanned data and it’s all twisted of datum…
So I applied a cylinder to an area of it that is cylindrical. I have then grouped this (plus other bits)

I am then able to relocate the gumball to the center line and midpoint of my cylinder so it is in a known position and on a known axis.

How do I then reposition all this using the gumball?

I can select the point on the cylinder center and move it to the datum but it is still all twisted and I was hoping to select the gumball arrow that is running through the cylinder axis and tell it somehow to point up along Z which would gain one axial direction and again to set the x etc…
but I am struggling…

All i can do is drag the group along the axis by pulling the gumball arrow.
if i select the move tool the gumball disappears.

are there any good instructional videos on YouTube that demonstrate how to straighten up twists 3d scan meshes like this??
