Kakao Talk Friends List
To send a KakaoTalk message to a user's KakaoTalk friend, you need to load the friend list.
The API to get the friends who joined the game and the API to get the friends who are not signed up are separate. Please use it according to your intended use.
The friends list comes down sorted by nickname.
The friend list is meant to be cached on the server.
Please note that the cache expiration time of the server is 10 minutes, but it may change according to the API policy.

When logging in to Kakao, the profile image and nickname (original text) information of unregistered KakaoTalk friends that were provided to a third party will no longer be downloaded. (Personal information issue)
From now on, only masked nickname and UUID (unsubscribed identification value) information can be downloaded.
The list of friends who have not joined the game cannot be exposed according to the game UI, and must be displayed in the game using the <Friend Picker> UI provided by the SDK API.
Friend Picker API
The friend picker UI is an API provided by Kakao, and the nickname is exposed in the original text on the user screen. When calling the API, the response value is provided as a ‘masked nickname’.
When calling the API, you can select from the 4 options below to link
