Proper way to show admin bar in HTML5 Blank theme

Having the same problem, I found the solution here:
https://pagecrafter.com/how-to-remove-filters-using-child-theme/

The thing is this:
1) do not touch the function in parent theme,
2) remove that filter in the child function.php in this way:

//Remove the filter that removes the admin bar
function remove_parent_filters(){ //Have to do it after theme setup, because child theme functions are loaded first
    remove_filter('show_admin_bar', 'remove_admin_bar');
}
add_action( 'after_setup_theme', 'remove_parent_filters' );
