electron: error while loading shared libraries: libgconf-2.so.4: cannot open shared object file: No such file or directory

I set up the app as explained in README. Installation was successful and running npm start throws an error. Here's the console output:

[demir@demirpc kmp-editor-0.5.2]$ npm start

> hlorenzi-kmp-editor@0.5.2 start /home/demir/mkwii-modding/kmp-editor-0.5.2
> electron .

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

Googling this error reveals that the GConf package provides this shared object file. Further searches reveal that GConf is obsolete and deprecated, and apparently an unnecessary dependency of some electron apps 1 2.
I kindly ask you to check if GConf is really still needed and update the dependency list accordingly. Thanks in advance and have a great day.
