How to add text to the toolbar?

Question

WordPress

I want to add just text to the toolbar, or more precisely, the number of the current version of WordPress.
But in the documentation and in all googled examples, a menu is added via add_menu.
So far, it has only turned out this way, but this is some kind of crutch.

add_action( 'admin_bar_menu', 'my_admin_bar_menu', 150 );
function my_admin_bar_menu( $wp_admin_bar ) {
  $wp_admin_bar->add_menu( array(
    'title' => 'Версия '.get_bloginfo ('version'),
  ) );
}

Tried it like that

add_action( 'wp_before_admin_bar_render', 'custom_toolbar', 99 )
function custom_toolbar() {
  bloginfo ('version');

}

But this does not display in the toolbar at all.

How can I display only text?
Additionally: I want to display it on the right, before the username. No matter what numbers I put in the hook, it is still displayed on the left side. How to display it on the right side?
