config Link not working

[mauro-montano]

Hi everyone!

I have ckeditor5 installed with strapi v4 and this config by default:

The problem is that always open the pages in a new tab no matter if you set Open in new tab to off, so i'm trying to change the config or adding a new button but no configuration works for me. I tried changing the ckeditor.txt or adding in plugins.js

Does anyone know how to edit the config to edit the buttons or add a new button to open the url in the same tab?
