Find and Replace RGB with CMYK Gradient fill problem

I have yet another  a major issue with CDR 2022 and its extends to previous versions as well.

I have a mesh object in RGB and need to converted all the RGB color to CMYK. The find and replace RGB Fills to CMYK does not work the same error NO OBJECT FOUND either selected or not.

Is there an efficient way to convert other than manually editing each point in the mesh.
