How can I add more than one tabbed page on one content page in xamarin forms?

Question

I have two different tabbed pages that I created, and the plan is to put them on one content page or single page, but I'm getting this error:

Error   XLS0503 A value of type 'HomeIncidentListTabbedPage' cannot be added to a collection or dictionary of type 'IList'.

Not sure how I would achieve this.

<ContentPage.Content>
    <ScrollView>
        <StackLayout>
            <Grid>
                <Grid.RowDefinitions>
                    <RowDefinition Height="*"/>
                    <RowDefinition Height="250"/>
                </Grid.RowDefinitions>

                <StackLayout Orientation="Vertical"  Grid.Row="0">
                    <Views:HomeTaskListTabbedPage/>
                </StackLayout>

                <StackLayout Orientation="Vertical"  Grid.Row="1">
                    <StackLayout HeightRequest="50" BackgroundColor="#004B21">
                        <Label Text="ACCIDENTS/ICIDENTS" TextColor="White" FontSize="Medium" VerticalOptions="StartAndExpand" HorizontalOptions="CenterAndExpand"/>
                    </StackLayout>
                    <StackLayout Orientation="Vertical"  Grid.Row="0">
                        <Views:HomeIncidentListTabbedPage />
                    </StackLayout>
                </StackLayout>
            </Grid>
        </StackLayout>
    </ScrollView>
</ContentPage.Content>
