Wordpress - Add submit button to admin toolar - wordpress

Question

I have my own function fsww_i_add_funds_request_daily that I wrote to perform the addition of a profit by a user based on the role of the user. This function was created / added for one plugin that I use. I am not sending any parameters to the function. I need to call this function using the submit button which will be on the admin toolbar. The function should be implemented in the plugin as it is necessary to use its "library" (maybe I spoke badly, I'm still a beginner in WP). How and where I need these functions implement?
Function
function fsww_i_add_funds_request_daily() {
require_once(dirname(__FILE__) . '/Wallet.php');
global $wpdb;
$query = $wpdb->get_results("SELECT user_id FROM {$wpdb->prefix}fswcwallet ORDER BY user_id ASC");
if($query) {
foreach($query as $user)
{
$user_id = $user->user_id;
$dailyProvision = 0;
if($user_id != 0)
{
$balance = fsww_price(Wallet::get_balance($user_id));
$last_deposit = fswcw_format_date(Wallet::get_last_deposit($user_id));
$status = Wallet::get_status($user_id);
$username = get_user_by('id', $user_id);
}
}
}
}
function fb_add_admin_bar_profit() {
global $wp_admin_bar;
$current_object = get_queried_object();
$wp_admin_bar->add_menu(
array( 'id' => 'addprofit',
'title' => __('Add profit'),
'href' => ?????)
);
}
add_action( 'admin_bar_menu', 'fb_add_admin_bar_profit');
Could you please help me with this?
