How to redefine default setting for sap.ui.richtexteditor.RichTextEditor

Hello,

I need to redefine default settings for the RichTextEditor control (to be specific - it's font size). If I understand correctly, this can be done using beforeEditorInit event. But I didn't find any description of the configuration object to be passed to the control.

I use the default editor type.

So how do I set the desired settings to the control?

Thank you.
