Is there a way to get the approval status of the user using php (for example: approved, awaiting email confirmation, etc.)
Yes, you have many examples in /includes/core/class-user.php
Also, can the program detect successful account activation? (email verification succeed)
Yes, by using these hooks in /includes/core/class-user.php
/**
* UM hook
*
* @type action
* @title um_after_user_status_is_changed_hook
* @description Action after user status changed
* @input_vars
* [{"var":"$user_id","type":"int","desc":"User ID"}]
* @change_log
* ["Since: 2.0"]
* @usage add_action( 'um_after_user_status_is_changed_hook', 'function_name', 10 );
* @example
* <?php
* add_action( 'um_after_user_status_is_changed_hook', 'my_after_user_status_is_changed', 10 );
* function my_after_user_status_is_changed() {
* // your code here
* }
* ?>
*/
do_action( 'um_after_user_status_is_changed_hook', um_user( 'ID' ) );
