In Magento 2.3 i'm trying to modify the link plugin to add a field to select a class for the link.
I had something like this in Magento1 :
I wish to have the same here in Magento 2.3 :
I tried to follow the TinyMCE4 doc https://www.tiny.cloud/docs-4x/plugins/link/ with the "link_class_list" option with no success.
Following the M2.3 doc did not help me, https://devdocs.magento.com/guides/v2.3/ui_comp_guide/components/ui-wysiwyg.html
What is the best way to add option to an existing plugin in magento 2.3 ?
