Overlays for 3DS?

I can’t seem to get Overlays to work on 3DS. On-screen overlay settings in Retroarch says ‘‘no settings found’’

Is there something I’m doing wrong? Also if overlays are not supported by the 3DS, is there a way to add handheld boarders to my games on 3DS

Hi there is my 3ds overlay. its possible to put overlay on 3ds core. i’m on windows
