I would like to create a report plugin where the link should be added to the navigation for every user (everyone who is logged in shall see the report).
Where in my plugin can I add this option?
I know that one can add a link in the admin menu in `settings.php` like this:
$ADMIN->add('reports',
new admin_externalpage('reportmyplugin', get_string('pluginname','report_myplugin'),
$url
));
But how can I add a link in the navigation block?
