What Gets 2nd Quantised in the WDW Equation: Geometry, Matter, or Gravity?

[Quantizer]

In QFT the background field is 2nd Quantised as opposed to remaining classical

What exactly gets 2nd Quantised in the WDW Equation

Geometry of SpaceTime
Or
Matter Energy
Or
Gravity
Or
Some combination of the above, if so what is the combination

here is an article covering WDW, which is probably what your looking for based on your your related posts.

you can easily find other papers showing a large variety of solutions by simply googling WDW equation. I would stick to the arxiv papers though lol. Thought you'd be interested in the paper.
