Probuilder Scene Icons & Polyshape Issue

I'm having 2 issues with ProBuilder and cannot find posts relating to the issue past 2020.

1) Every probuilder tutorial I come across they have additional icons in the left side of their scene view for grid snapping, how can I enable these?


2) When using the polyshape tool, vertices do not snap to the grid even though grid snapping is enabled.
I can create a new shape and snap it along the grid, but the poly tool only seems to be working as free placement making all my walls have slightly off angles. How do I enable grid snapping for the polyshape tool?

 

Same problem here
It seems there're only unanswered threads on that issue around
The tool appears really basic (if not useless) if this functionality is non-existent...
