sorry if this is in the wrong place.
I want to take out the ability for authors to change the typography sizes in either Gutenberg or DIVI. We have a number of users that are unable to follow guidelines. For everything they do, they could just use the normal default. But I am unfamiliar with editing the themes in WP and am not sure where I would go about making this edit:
‘add_theme_support(‘disable-custom-font-sizes’);’

Also both DIVI and Gutenberg are available to them.
