Custom render pass that affects UI

Hey
I'm trying to do a custom renderpass that acts as a post effect on the entire screen output. I've created a renderer with the Render Objects renderfeature - in there I've added my own material with a custom shader I made I shader graph. And that actually somehow works..!
Except I can't get it to affect the UI elements. The UI canvas is set to "screenspace camera" and other post effects (from post effect volume) are affecting the UI, but just not my custom render object effect.

Is there something I'm missing, is it not possible?


The custom effect stretching the image
