Update #1:
After asking from @leymannx I checked how these settings are stored.
It turned out that settings are not permanent, they are saved in the browser as localStorage.
key: WP_DATA_USER_{id}:
value: {
"core/nux":{
"preferences":{
"areTipsEnabled":false,
"dismissedTips":{}
}
},
//"core/edit-post"
//...
Update #2:
Gutenberg tips can be disabled by using dispatch('core/nux').disableTips() (NUX package) and action hook enqueue_block_editor_assets.
file functions.php:
function se334561_editor_tips() {
wp_enqueue_script(
'se334561-js',
// --- to use in plugin ---
// plugins_url('/disable-tips.js', __FILE__),
get_stylesheet_directory_uri() . '/disable-tips.js',
array('wp-blocks')
);
}
add_action('enqueue_block_editor_assets', 'se334561_editor_tips');
file disable-tips.js:
jQuery(document).ready(function(){
var isVisible = wp.data.select('core/nux').areTipsEnabled()
if (isVisible) {
wp.data.dispatch('core/nux').disableTips();
}
});
