Need help with ACES workflow while using generative fill

I know there's already some post about ACES workflow but I can't seem to find a post that fits my scenario. This is a 2 part question:

1. I'm working on a project and recieved some footage (.exr) in ACEScg color space. I'd like to take a frame into photoshop and use some generative fill to create a clean plate, but Photoshop doesn't seem to like 32 bpc. Is there a workaround for this without changing the color space/ bits?

2. I need help with color management in general. The client is asking to review the clips in a ACES sRGB - Texture color space. I'm not sure how to do this with the OCIO plugin. I'm pretty sure I will have no problem for the final delivery of keeping ACEScg color space, but not sure about the review.

Hopefully that makes sense!
