Exporting stills on DaVinci Resolve using ACES (DCI to rec709)

I’m workiing on a project that I’m mastering on P3-DCI. I have to send to client jpegs for approval, but there’s the color transform problem. Even when I change my ODT to rec709, the jpegs are still in DCI-P3. How do I export the stills in the proper color space? Any advice?
