Rider 2021.3 - Unity3d C# syntax color highlight?

hello,

just want to switch from VCCode to Rider for Unity3d.

i'll need to customize the Rider interface that worked well...

but unity3d color highlight is not implemented...

there are a lot missing like: float, int, long, sting ....

also: GameObject, Rectransform, Transform, KeyCode etc...

here is a example how my theme with Unity3d C# syntax color highlight looks like...

in VScode it's very easy to add to existing syntax color highlight like to add to c#

also missing better documenation about the UI coloring... what elements hav which function...

best would be a screenshot with numbers and corresponding description...

would make to design a color scheme much easier...

how can i'll add Unity3d C# syntax color highlight by myself?
the 4 user adjustable extra color highlight is not enough...
and i'll want to make a community theme for Unity3d users...
so need to add Unity3d C# syntax color highlight to the theme...
@ moment looks like impossible...
if someone can help me plz plz
Unity3d C# syntax color highlight is very important to us Unity C# user!
many thx
M.
