Exporting footage in LogC3 color space

Hello,

I am a picture editor on a feature film shot on LogC3 (via Alexa Mini). We're in the final stages and VFX need to be done on a few shots. I provided an exported shot for VFX and the colorist noted that it was in the wrong color space (Rec709). I've tried doing some research on how to export the footage from Premiere so that it's in the right color space but I'm confused if this is possible in Premiere from the mixed reports. Is it?

I tried overriding the color via Modify > Color > Override Media Color Space > ARRI LogC3/Wide Gamut3 but then the footage looks wonky, like it's a LUT instead of Flat. Can anyone advise? Thank you.
