Dynamic content is not working in Grapesjs email builder

Hi everyone!

Dynamic content does not work in Grapesjs email builder.

I searched here on the forum and found this (Update grapesjs to version 0.21.8 (Mautic 4) by LordRembo · Pull Request #13285 · mautic/mautic · GitHub) with a fix for this issue.

Will this fix be available for Mautic 4? If not, how do I apply the fix to my Mautic? Is there a tutorial?

For Mautic 5, is dynamic content working with Grapesjs?

Thank you and I appreciate any help from the community.
