I'm using Joomla 3.10.12 and latest version of JCE Editor, along with SP PageBuilder 3.x.
I found the article: https://www.joomlacontenteditor.net/support/faq/editor/editor-xtd-buttons-missing that explains how to add the xtd-buttons to the JCE Editor in SPPB, but for some reason that specific button isn't appearing, although it does in the core article manager.
Here's a short video overview: https://ln5.sync.com/dl/110d33b30#eh8tw5wq-5g4q76g3-4jhr4raz-uiksatqz
I look forward to any help you can provide.
