Thank you for your reply. The installation instructions for this plugin say that you need to do this via the command line (console) and then deploy/build it (if I understand correctly).
I will try to install this plugin, but I am not sure I can do it via the console… Unfortunately, I am not an expert in coding and do not have the skills to work in the console. I could not find any information about this plugin. Can it be downloaded via the web interface for installation?
Or is there another way to easily install the plugin for a non-programmer?
