Sylius Export Import plugin

Hello! I am recently installing a plugin for sylius, which is called SyliusImportExport-Plugin. Aparrently they do not define where to put the code with the headline: “Application configuration” ( ). I tried to put it in the plugin.yaml file which gets importet from the services.yaml file, but it’s not working out. The error message tells me that there is no extension able to load the configuration for “fos_sylius_import_export”. Maybe any of you guys can help me out or give me some tips to solve my problem.

The code that I added:

It dosn’t really matter where you put that configuration as far as it’s loaded.
A good place for it would be config/packages/fos_sylius_import_export.yaml (the file name matches the configuration root name).
