How do to change the gridSteps of the grid?

[cima-to-sa]

I would like to change the structure (not the spacing of the main grid or sub-grid) of the grid from a default 4x4 sub-grid to e.g. 5x5 sub-grid.

There's a configuration parameter described (gridSteps: https://www.drawio.com/doc/faq/configure-diagram-editor) of which I think it's the right one. However, it does not change the the gridSteps as expected. It seems that this issue has already been discussed (#1249) but not really sure if successful.

draw.io desktop, v24.6.4

Thanks for any help or tips. this is how the configuration looks like:
