Remove dashboard widget

Hi,

I would like to remove the ‘WordPress Guides/Tutorial’ widget which get added to the dashobard when activating the plugin.

I know how to hide it with the ‘screen options’ way but I can also do it within my functions.php file like:

remove_meta_box( 'dashboard_plugins', 'dashboard', 'normal' );

But what’s the name of the widget? I already searched the plugin code but couldn’t find it with a quick search.

Thanks in advance!
