How to automatically create a user profile from 1C and remove it from the external sale group?

Question

1C-Bitrix

Colleagues, I'm asking for help, I'm importing users from 1C, for some reason they fall into the EXTERNAL_AUTH_ID = sale group, I have to manually delete them from the database. you can’t set a password for them in this case, then
I write in init.php to create a profile during registration, but it only works for manual registration.

AddEventHandler("main", "OnAfterUserRegister", Array("MyClass", "OnBeforeUserRegisterHandler")); 
class MyClass
{
    function OnBeforeUserRegisterHandler(&$arFields)
    {
      //создаём профиль
      //PERSON_TYPE_ID - идентификатор типа плательщика, для которого создаётся профиль
      $arProfileFields = array(
         "NAME" => "Профиль покупателя (".$arFields['LOGIN'].')',
         "USER_ID" => $arFields['USER_ID'],
         "PERSON_TYPE_ID" => 3
      );
      $PROFILE_ID = CSaleOrderUserProps::Add($arProfileFields);
      
      //если профиль создан
      if ($PROFILE_ID)
      {
         //формируем массив свойств
         $PROPS=Array(
         array(
               "USER_PROPS_ID" => $PROFILE_ID,
               "ORDER_PROPS_ID" => 3,
               "NAME" => "Телефон",
               "VALUE" => $arFields['WORK_PHONE']
            ),
         array(
               "USER_PROPS_ID" => $PROFILE_ID,
               "ORDER_PROPS_ID" => 1,
               "NAME" => "Ф.И.О.",
               "VALUE" => $arFields['LAST_NAME'].' '.$arFields['NAME'].' '.$arFields['SECOND_NAME']
            )
         );
         //добавляем значения свойств к созданному ранее профилю
         foreach ($PROPS as $prop)
            CSaleOrderUserPropsValue::Add($prop);
      }
    }}

Tried changing to

AddEventHandler("main", "OnAfterUserAdd", Array("MyClass", "OnBeforeUserAddHandler"));

Causes errors :(
