Part Number: CODECOMPOSER
In CCS Eclipse I have the "Include browser" view, where I can see what is inluded by a file, and who includes this file.
(file = C source file)
Example:

I can't find similar tool in CCS Theia.
I did find an extension "include tree" but that require I have a gcc or clang compiler + that I manually copy all the include path's from the CCS project into this tools configuration. Not really usefull.
Any advice?
