Xamarin forms Add button in TabbedPage

I have a question. I created the following TabbedPage:

<?xml version="1.0" encoding="utf-8" ?>
<TabbedPage xmlns="http://xamarin.com/schemas/2014/forms"
            xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
            xmlns:d="http://xamarin.com/schemas/2014/forms/design"
            xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
            xmlns:views="clr-namespace:MyApp.Views"
            mc:Ignorable="d"
            x:Class="MyApp.Views.MainPage"
            xmlns:android="clr-namespace:Xamarin.Forms.PlatformConfiguration.AndroidSpecific;assembly=Xamarin.Forms.Core"
            android:TabbedPage.ToolbarPlacement="Bottom"
            BarBackgroundColor="White"
            BarTextColor="Black"
            android:TabbedPage.BarItemColor="#B2B2B2"
            android:TabbedPage.BarSelectedItemColor="#56D7A5"
            android:TabbedPage.IsSwipePagingEnabled="False">    

    <TabbedPage.Children>
        <NavigationPage Title="page1" IconImageSource="navbar_page1">
            <x:Arguments>
                <views:page1 NavigationPage.HasNavigationBar="False" />
            </x:Arguments>
        </NavigationPage>

        <NavigationPage Title="page2" IconImageSource="navbar_page2">
            <x:Arguments>
                <views:page2 NavigationPage.HasNavigationBar="False" />
            </x:Arguments>
        </NavigationPage>

        <NavigationPage Title="page3" IconImageSource="navbar_page3">
            <x:Arguments>
                <views:page3 NavigationPage.HasNavigationBar="False" />
            </x:Arguments>
        </NavigationPage>
    
</TabbedPage>

Now on every page I have added this custom FabMenu like this:

<c:FloatingMenu Margin="0, 0, 10, 10" BGColor="#56D7A5" OpenIcon="openFab_icon" CloseIcon="closeFab_icon"
                AbsoluteLayout.LayoutBounds=".95,.95" AbsoluteLayout.LayoutFlags="PositionProportional">
    <c:FloatingButton x:Name="btnAddHomework" BGColor="#59E1FF" IconSrc="add_homework_icon" OnClickCommand="{Binding btnAddHomeworkCommand}" />
    <c:FloatingButton x:Name="btnAddDeadline" BGColor="#0FF1A0" IconSrc="add_deadline_icon"/>
    <c:FloatingButton x:Name="btnAddTest" BGColor="#5988FF" IconSrc="add_test_icon"/>
</c:FloatingMenu>

The problem is that every page has his own FabMenu, so you see it dissapear and reappear on every page, so my question is: Is there some kind of root view that overlays all the tabs in the TabbedPage?

Please let me know how I do that!
