Adding multiple plugins together

Hello all,

I have encountered a problem when trying to add 2 plugins together for example: grapesjs-preset-webpage and grapesjs-plugin-ckeditor. I downloaded both via npm, imported them and added to the plugin field at grapesjs.init.

this.editor = grapesjs.init({ plugins: [ckEditorPlugin,grapesjsPreset], ... })

For some reason ckeditor is not recognized and there is no sign for him. Any ideas will be appreciated.
