Hi,

using the RTE configuration Full.yaml the defined buttons or the possible features don't appear unless additional config is set.

E.g. there is the toolbar item showBlocks defined, but it only works, if you either set the extraPlugins config

        extraPlugins:
            - showblocks

or if you set the importModules config manually

        importModules:
           - { module: '@ckeditor/ckeditor5-show-blocks', exports: ['ShowBlocks'] }

Same for the word-count plugin, which is available, but not added to the Full.yaml configuration.

        extraPlugins:
            - wordcount

or

        importModules:
           - { module: '@ckeditor/ckeditor5-word-count', exports: ['WordCount'] }

Using the config extraPlugins has a additional pitfall: For the toolbar item example 'showBlocks' the extraPlugins setting has to be 'showblocks' or 'ShowBlocks' but NOT 'showBlocks'. Maybe the mapping of the plugins could simply be case insensitive?!.

Thanks for analyzing and fixing the issue.
