Question Local PostProcessing override Volumes for 2D?

The Net is full of tutorials on ALL versions of postprocessing in Unity at the same time - stack version1, version2... PostProcessingVolume, Layers ... outdated and not outdated...

-I'm lost

Please help - where can I see an example of using _Local_ volumes for the version of Postprocessing integrated in the URP, in the case of a 2D game with a camera fixed in the center of the level?

An important clarification - with global volumes - I have no problems, -URP postprocessing works fine,
but I just can’t make the local volume work with Postprocessing Override for the case when the hero (or another object) enters the collider of this volume...

Is it possible? Or these "volumes" work only for the Camera?
(although even with the camera I still haven’t succeeded ...)

help...
