I've installed JCE Editor Pro v. 2.9.11 on a Joomla 4.0.2 site. I'm missing certain icons in the layout that normally would be available in a Joomla 3.x site. For instance iFrames, Image Manager Extended, Columns. So I'm unable to add them to the layout I've assigned to myself. They are not available to the default user profile either. In other words, there is no button to drag.
I've installed the Media Manager plugin as well. And I'm attaching the screenshot for the layout of the editor.
What am I missing?
