Monowidth font in GrapesJS code viewer and editor

My idea is
Replace Arial with a font suited for displaying code.

For example: Roboto Mono - Google Fonts

I think these groups of people would benefit from this idea:
Those who send emails and building landing pages.

Why I think they would benefit from this idea:
Easier to edit email and page code.

Any code or resources to support this idea:

Are you willing to work on this idea?:

What skills and resources do you need to explore this further?

Hi,
You can add google fonts by using

https://documentation.mjml.io/#mj-font

Example:

 <mjml>
   <mj-head>
     <mj-font name="Roboto"
       href="https://fonts.googleapis.com/css?family=Roboto" />
   </mj-head>
   <mj-body>
     <mj-section>
       <mj-column>
         <mj-text font-family="Roboto, Arial">
           Hello World!
         </mj-text>
       </mj-column>
      </mj-section>
   </mj-body>
 </mjml>

However, plz be aware, that your font won’t be visible for most of your readers:

But it’s not the email font I want to change. It’s the font used in the code editor:
