How to use the ScaledReordered class with Reordering

[QuasarJSPark]

hello. I am using Ginkgo solver and getting satisfactory performance.

To improve the execution time, I recently applied RCM/AMD reordering method and got some effect. Additionally, we found that Ginkgo provides ScaledReordered.

Currently, the Jacobian matrix that is generated from us has a large difference in scale between the main diagonal component and the off-diagonal component due to a problem in the simulator implementation. In this case, we want to try to improve convergence by using ScaledReorder.

However, for the ScaledReordered class, I can't find any example code, although some test code exists. Could you please provide a suitable ScaledReordered example code for an preconditioned-iterative solver case?
