preview mode - Toolbar Buttons are not disabled (Edit Code/Live Code/Preview Code/Toggle fullscreen)

[JieunSon96]

On the preview mode, <MDEditor preview={'preview'} /> currently if it is the preview mode (disabled to type) it disables the toolbar options on the left like bold, Italic bts but not the buttons on the right(Edit button,Live code, Preview Code etc)

Is there any way to disable the right toolbar options if it is in preview mode?
