[Repro linkLineID:@"LINE_USER_ID" lineChannelID:@"LINE_CHANNEL_ID"];

// Set user ID first
Repro.setUserID("user123")

Repro.linkLineID(lineUserID: "LINE_USER_ID", lineChannelID: "LINE_CHANNEL_ID")

// Set user ID first
Repro.setUserID("user123");

// Link LINE User ID
Repro.linkLineID("LINE_USER_ID", "LINE_CHANNEL_ID");

// Set user ID first
Repro.setUserID("user123")

[Repro unlinkLineID:@"LINE_USER_ID" lineChannelID:@"LINE_CHANNEL_ID"];

Repro.unlinkLineID(lineUserID: "LINE_USER_ID", lineChannelID: "LINE_CHANNEL_ID")

Repro.unlinkLineID("LINE_USER_ID", "LINE_CHANNEL_ID");
