As it says in the docs (in the link you provided) that was depreciated in 2017…
Warning: This option has been deprecated on Jul 18, 2017. Applications created after this date will not be able to access it (but it will still be applied in run mode). Instead, users can use a condition on the action and create the thing if it does not exist in an action prior to the Change Thing action. We recommend users using this option to follow the same pattern as they upgrade their apps.
