5.3 OpenColorIO/OCIO Texture Conversion?

Hello, I’m trying to convert textures with OpenColorIO in the Unreal Editor (read them in with the correct IDT for a conversion to the working color space). Unreal 5.3 allegedly added this functionality-

But, on texture objects I don’t see any settings pertaining to OCIO (I have the plugin enabled and an OCIO config object set up), and this guide is the same between 5.3 and 5.2-

Any help would be appreciated!
