X11 folder for Matlab R2019b

How can I get X11 icon image files for MATLAB RT R2019b on Linux,

This folder is called "X11" containing image files for MATLAB and Simulink icons

Such directory has been provided for R2014a - https://www.mathworks.com/matlabcentral/answers/121430-how-can-i-get-x11-icon-image-files-for-matlab-r2014a-on-linux

Is it possible to recieve such folder suitable for R2019b?

Thanks
