UE Custom Post Process

Hello UE developer, I have added a plugin called Lens Destruction based on the documentation. Then I added a custom implemented post-processing plugin, which I indicated in the SubscribeToPostProcessingPass function that the injection point is in EPostProcessingPass: VisualizeDepthOfField. But there is no post-processing effect in the Game window after passing through the Lens Distortion plugin. Is there a solution?
