I am currently new to Geant4 and Linux. I am currently trying to recreate a sample simulation of G4Sipm (external software package) after having installed Geant4 (version geant4.10.06.p02). It does run the command however no GUI window for graphical representation of the simulation is shown as suggested by this documentation https://g4sipm.readthedocs.io/en/latest/sample.html instead it gives me this

Any help or advice is greatly appreciated (I tried both enabling both open GL and QT options for the software package as I installed them in Geant4 but to no avail).
