OCIO Colour Management Not Available in Linux

While using Substance Painter 2021.3.0 in Linux, I cannot access any of the OCIO colour management options. I've tried looking in the 'New Project' & 'Project Configuration' windows, as oultined by this page: https://substance3d.adobe.com/documentation/spdoc/color-management-with-opencolorio-225969419.html

Is this a known limitation of the Linux version of Substance Painter? Are there any plans to update this?

Thanks,

Joe
