Postprocessing problems in mobile like outlining in ue5

Hi everyone,
Was testing out outlining objects using unreal engine 5. Created an interactive outline material for the same, and also had a post process volume, which had the following material as asset reference. The problem is this works perfectly for windows. In mobile, I noticed that no outline is formed.
Usually, we enable mobile HDR, and then enable r.Mobile.TonemapperFilm or set it to 1 for postprocessing in mobile.
There was no “r.Mobile.TonemapperFilm” command in unreal, and both the command console and engine.ini settings do not recognize the same. Any workaround for this. Please update if something is changed.
