void UMyGame::RefreshToken(const FString& RefreshToken)
{
    // Create request body with player information
    TSharedPtr<FJsonObject> Body = FPlayNANOOHelper::CreateRequestBody();
    Body->SetStringField(TEXT("refresh_token"), RefreshToken);

    Request->SetVerb(TEXT("PUT"));
    FPlayNANOOHelper::SetCommonHeaders(Request, false);  // No authentication token required
    Request->SetContentAsString(JsonBody);

    Request->OnProcessRequestComplete().BindLambda(

    {
        if (bSuccess && Res.IsValid())
        {

            if (FJsonSerializer::Deserialize(Reader, JsonObject))
            {
                // Token information
                const TSharedPtr<FJsonObject>* TokenObject;
                if (JsonObject->TryGetObjectField(TEXT("Token"), TokenObject))

                    UE_LOG(LogTemp, Log, TEXT("Token refresh successful"));
                }

                // Player information
                const TSharedPtr<FJsonObject>* PlayerObject;
                if (JsonObject->TryGetObjectField(TEXT("Player"), PlayerObject))

                }
            }
        }

    Request->ProcessRequest();
}

When to Refresh Token

When the access token expires and you receive a 401 Unauthorized response, issue a new access token using the refresh token.
