WOOCOMMERCE call function from URL - php

Question

I have a php function that creates a new session (WC()->session->set).
I want to make a link on site's header that calls a function to remove that session ( WC()->session->set( 'the_session', null );
how it should be done? couldn't find a way :(
tried to use $_get on functions, which didn't work
EDIT:
here is the code Im using, it add's the option to edit orders that have been made already:

return $statuses;

// 2. Add Order Actions # My Account
add_filter( 'woocommerce_my_account_my_orders_actions', 'bbloomer_add_edit_order_my_account_orders_actions', 50, 2 );
function bbloomer_add_edit_order_my_account_orders_actions( $actions, $order ) {
if ( $order->has_status( 'processing' ) ) {

$credit = $order->get_total();
wc_print_notice( 'A credit of ' . wc_price($credit) . ' has been applied to this new order. Feel free to add products to it or change other details such as delivery date.', 'notice' );

// 6. Save Order Action if New Order is Placed
add_action( 'woocommerce_checkout_update_order_meta', 'bbloomer_save_edit_order' );
function bbloomer_save_edit_order( $order_id ) {

if ( ! empty( $edited ) ) {
// update this new order
update_post_meta( $order_id, '_edit_order', $edited );
$neworder = new WC_Order( $order_id );
$oldorder_edit = get_edit_post_link( $edited );
$neworder->add_order_note( 'Order placed after editing. Old order number: ' . $edited . '' );
// cancel previous order
$oldorder = new WC_Order( $edited );
$neworder_edit = get_edit_post_link( $order_id );
$oldorder->update_status( 'cancelled', 'Order cancelled after editing. New order number: ' . $order_id . ' -' );
WC()->session->set( 'edit_order', null );
}
}
I want to make a button on my website header, that removes the session after the user clicked "edit order", if he decided to cancel the editing and stay with his original order, the line that does that is
WC()->session->set( 'edit_order', null );
and I want it to be a link

Answer 1

Found the right way:
add_action('afterheader','leave_edit_order');
function after_header_block_yhm()
{
do_action( 'afterheader');
}
add_shortcode('under_header_location','after_header_block_yhm');
function leave_edit_order(){
$edited = WC()->session->get('edit_order');
if(!empty($edited) && isset($_GET['cancel_edit_order'])){
WC()->session->set( 'edit_order', null );
wc_print_notice( 'You left "edit order" session, enjoy your stay.' );
}
add_action('afterheader','leave_edit_order');
Made a new action called 'afterheader" and a new shortcode called 'under_header_location',
then used elementor to put the shortcode in the place I wanted, and then called the function in that new action I made
on the function Im checking that the user has ?cancel_edit_order on his url and then calling the function
