Pass parameters to shortcoder

I had created a shortcode in functions.php, but would like to use shortcoder for it. The code is below. The question is, how can I pass the $atts and $tag attributes to shortcoder? Typical usage is [wbpsb title=”first%20degree%20rage”].

function wbpsb_shortcode($atts = [], $content = null, $tag = '')
{
    // normalize attribute keys, lowercase
    $atts = array_change_key_case((array)$atts, CASE_LOWER);
 
    // override default attributes with user attributes
    $wbpsb_atts = shortcode_atts([
                                     'title' => 'WordPress.org',
                                 ], $atts, $tag);
 
	// load sales buttons for this title. The title is all lowercase using every word in the proper title with %20 in place of spaces. Here are some example formats for the title:
	//  lockout
	//  paper%20wings
	include "https://wildbluepress.com/wp-content/themes/magazine-pro/wbp-maincontentsalesbuttons.php?title=".$wbpsb_atts['title'];
 
    // return output
    return $o;
}
 
function wbpsb_shortcodes_init()
{
    add_shortcode('wbpsb', 'wbpsb_shortcode');
}
 
add_action('init', 'wbpsb_shortcodes_init');
