Have you looked through this documentation? https://world.episerver.com/documentation/developer-guides/CMS/add-ons/customizing-the-tinymce-editor-v2/
There are several related subtopics under this topic.
Thanks for your attention.
Yes I have read the documentation with subtopics several times :).
To me it seems these plugins does no longer exist.
The plugin is called: quickbars and then you can do something like this:
.Toolbar("undo redo cut copy paste removeformat");
First, let me appologize if this post is in the wrong forum.
I've done some research and I cannot seem to find wether these buttons exist in the new version of TinyMCE.
Can someone please help me with the plugin names if they exist, or possibly suggest alternative step to include a field form another page (dynamic content button)
