Remove tabs and fields for roles

Hi,

I know this is an old topic, I have found many threads here, but some just pointed in the general direction of somewhere WordPress, and actual code that was given did not work. Perhaps because those posts were too old. Those were all about metaboxes, and I guess those are now panels and meta fields in Gutenberg. So perhaps this isn’t even a GeneratePress question, although I’d like to hide GP controls in particular.

What I need, is to remove some of the tabs and fields for roles other than admin. Not everything, just the layout tab, for example, or “object fit” in the image block settings.

Theoretically one could just hide those fields with CSS:

function hide_meta_boxes(){if(!current_user_can('administrator')) { /* hide beckground color setting */
echo '<style>.components-tools-panel-item.block-editor-tools-panel-color-gradient-settings__item.last { display: none !important; }</style>'; }}
add_action('admin_head', 'hide_meta_boxes');

But is that the best way?

Thanks!

EDIT: I now looked at the editor source, and found why CSS is no good. None of the boxes have safe classes to access them. GP panels all have the same class: components-panel__body gblocks-panel-label
Even elements inside the panel have no unique classes. The only way I see is nth-child(). But if anything ever changes in the panel order, the CSS will break.
