I'm trying to add some data to the end of the admin orders listing page below the lower Details and Edit buttons on the right side of the page. I'm using the NOTIFY_ADMIN_ORDERS_MENU_BUTTONS_END notifier to trigger the code. But your Edit button gets displayed last, after my data is displayed.

How can I force my code to display last? I guess the basic question I have, which has arisen before and I have found no solution yet, is how to control the execution order of observers when multiple observers are triggered by the same notifier. I would like the solution to be elegant, but any solution that works would be appreciated.

My observer is auto loaded and contains code for multiple notifiers in admin/orders.php. zc157c, PHP 7.3, Edit Orders, SBA addon's in admin.
