Custom Coordinate System EPSG:3411 for desktop AND FME server

I have a coordinate system definition from a ESRI shape *.prj -file.

It seems to be EPSG:3411, even if there are small differences in the definition.

How can I create a costum coordinate system to use on both FME desktop and server?

The tool her https://demos-safe-software.fmecloud.com/fmedatastreaming/Coordsys/Start.fmw does not work.

I would appreciate any help with this:

Thanks.

Here are the definitions:
