How to improve meshing (reduce skewness + display nonOrthogonality)

Greetings.

I am trying to improve my mesh as I read that skewness for hexahedral needs to be below ~0.85.

I want to work on the bad region and improve rather than starting from scratch!
I came across this video (https://www.youtube.com/watch?v=6fPnS0Ce5XQ) where I can preview non-orthogonal mesh. However, I am unable to get the option in ParaView?

Is there a specific command that I need to type for OpenFOAM (like FoamToVTK) to get that option so I can improve just the bad region?

I have attached my meshing and the checkMesh message.

Any help is appreciated.
