Hi,Does anyone know how can I customize a rich text from a Content fragment? I want to apply a background color to the text, something like in below image

Hi all,I want to add new functionality for image for the rich text from Content Fragment.I tried to do manually overlaying the StyleTextEditor.js files from /libs under /apps and I enabled image#imageProps but without success.Does anyone any idea how to resolve that?

I tried to enabled image#imageProps but doesn't work. I don't know why the files under admin are like disable or something like this.I want to add a property in rich text for the image (align: left, right).
