3x3 Max Filter in Grapher

Hi - I am trying to automate a S2 processing chain which includes the Maximum 3x3 non-linear filter.

I cannot see a way of adding it in Graph Builder - the options only allow specification of a custom kernel, which has been covered in another topic. Does anyone have any advice about how to batch-script this function?


As said in this topic -> Where is Image Filter option in Raster menu? , the Image filter operator is not a perfect replica of what you can do using the user interface of SNAP-Desktop. The operators on the graph builders suffer from the same problems
