How to smooth or blur react-postprocessing SSAO

Hi,
is possible to blur or smooth the SSAO effect? I was trying to obtain a result like shadows.
I can’t find the way, i tried with fade params of SSAOEffect but nothing better.
I was working on this example, given by react three.

Thank you

AO has quite a lot of parameters, but the docs are the best place to study them SSAOEffect | postprocessing

I searched, but nothing that gives me what i want. Maybe is better using SAO, that has the “blur” param.
Thanks anyway
