admin aoolbar add_node() and pulling in my post slug

if you want to customise the links in the backend list, you can use this filter :

add_filter("post_row_actions", function ($actions, \WP_Post $post) {

    if ("custom_post_type_slug" === $post->post_type) {

        // modify a existing action or add a new in $actions

        $actions["other link"] = "<a href=\"url\">other link</a>";

    }

    return $actions;

}, 10, 2);
