PCSX ReARMed, the rumble feature is not working on Android

Sorry if this has been covered already.

I read that the said Core does have rumble compatibility but it’s not working on my Final Fantasy VIII (ripped from the CD, not downloaded). I’ve tried many options but can’t seem to pinpoint the right settings to get it to work. Used a genuine PS4 controller and one I just bought with a proper turbo button (cause the integrated one RetroArch uses makes no sense).

video I made showing my issue.
