How to highlight newly added item to CollectionView

I am using Xamarin forms.I have CollectionView in Xamarins showing List of Tickets.I want to highlight new rows whenever its inserted.Like flashing or blinking the row with red background say for 5 seconds.After 5 seconds it should be normal row. Clients will add rows in real time using SignalR.

<CollectionView.ItemTemplate>

                        <Frame x:Name="frame1" BackgroundColor="White" BorderColor="#F0F0F0" Padding="3" Margin="0,0,0,5" HasShadow="False" CornerRadius="10" DescendantAdded="Frame_DescendantAdded">
                            <Grid HeightRequest="40" HorizontalOptions="FillAndExpand" VerticalOptions="Start">
                                <Grid.ColumnDefinitions>
                                    <ColumnDefinition Width="2*"/>
                                    <ColumnDefinition Width="2*" />
                                    <ColumnDefinition Width="6*" />
                                </Grid.ColumnDefinitions>

                            <Label Grid.Column="0" x:Name="lb_TicketNumber" Text="{Binding TicketNumber}" TextColor="Black" FontSize="Large" FontAttributes="Bold" VerticalOptions="Center" Margin="20,0" HorizontalTextAlignment="Center"  />
                            <Label Grid.Column="1" Text="{Binding DeskName}" TextColor="Black" FontSize="Large" FontAttributes="Bold" VerticalOptions="Center" HorizontalTextAlignment="Center"/>
                            <Label Grid.Column="2" Text="{Binding ServiceNameEng}" TextColor="Black" FontSize="Large" FontAttributes="Bold" VerticalOptions="Center" HorizontalTextAlignment="Center" />

                            </Grid>

                        </Frame>

                </DataTemplate>
            </CollectionView.ItemTemplate>

        </CollectionView>
