Dark Edges - Chroma Key

Hi guys!
I hope Im asking this in the correct place!
I was wondering is there is any way on OBS to "erode/ Dilate" the alpha of a green screen camera source, after the chroma key?? So as to get rid of the dark edge??
Maybe the "erode" term is more familiar to the ones that do VFX, but basically what I want to do is to contract/reduce/dilate the size of the alpha so as to get rid of the dark edge.
Here is an example (left image is what I get on OBS, right image just a photoshop of the result I want):

This usually appears when adding color adjustments to the source, after the chroma key. But even without doing it, by default it already has an edge.
If anyone has a solution for this, I will really appreciate it!
Thanks in advance!
