Change colors of context help window. How to ?

[JerryMC22]

Hello,

how I can change the terrible colors in context window in actual CubeIDE ? I see white background and white text. It is terrible. And  - by the way - why I can not instal the darkest dark theme ? I see a terrible error - see images below.

I found the reply to the first question:

Window / Preferences / C/C++ / Editor / Source Hover Background.

Unfortunateley, the DarkestDarkTheme still defies to be installed :(
