Is your feature request related to a problem? Please describe.
Currently, the rich text field is editable only in the side drawer. It can be limiting sometimes especially if you are using it to create long-form blog content. The rich text field type can use a fullscreen mode similar to the markdown field.

Describe the solution you'd like
Currently, the markdown field in side drawer has a button to expand it to a full screen mode, as show below.

We need a similar button in the richtext field to be able to expand the view to full screen mode.
