Move pivot point in script

It seems like most of the top results for this were overly complicated, what I did was this:

 // Center Pivot
 private Vector2 expandPivot = new Vector2(0.5f, 0.5f);
 
 //method:
 TMP_object.rectTransform.pivot = expandPivot;

So, basically, just get the rect transform and assign a 2d vector to it's pivot property. Necro posting because maybe this has changed in the last 8 years.
