How do I apply URP postprocess to a UI image?

I made a dissolve shader after watching this tutorial, [Sprite Dissolve - 2D Shader Graph Tutorial](https://www.youtube.com/watch?v=auglNRLM944). I applied the shader to an UI image and created a post-process volume for the camera, the problem is that the bloom won't affect the shader unless I set the canvas to **Render Mode => Screen Space - Camera**. I there a way to see the post-process and leave the Canvas's render mode to **Screen Space - Overlay**?
