When the Connect Account API which uses the basic account connection UI is called, a window appears as below asking you to decide which IDP you will use.
Image RemovedImage Added
In the event that the developer wants to implement the account connection UI (i.e. the developer does not want to use the basic account connection UI), connect account API by IDP is provided. In this case, a connect account button for each IDP should be placed in the account connection screen, and when each button is clicked, the connect account API for each IDP should be called.

5.1.3. Connect accounts not using the basic account connection UI

The following is an example of connect account not using the basic account connection UI.

Connect to other IDP accounts is available only after the guest, SIWA(in Korea, iPhone only) has been authenticated. Otherwise, you have to deactive the account connection UI.
If connect account is successful, the player ID is maintained.
