Fullwidth Page Builder Option

I have successfully modified the size of the text-block page builder popup – but I’m stuck on how to make each of the options run full width as well.

I have edited the text-block size by recreating the config file in my theme:
'popup_size' => 'large'

Here is an example https://i.imgur.com/wUYASjQ.png?1 – as you can see, I want the WYSIWYG editor to fill the entire popup.
