How to insert (instead redefine) context menu item in MAUI.NET control

Question

I did a context menu for the control as described in tutorial: https://learn.microsoft.com/en-us/dotnet/maui/user-interface/context-menu It works perfect.

<Entry ...>
    <FlyoutBase.ContextFlyout>
        <MenuFlyout>
            <MenuFlyoutItem Text="..." Command="..." CommandParameter="..." />
        </MenuFlyout>
    </FlyoutBase.ContextFlyout>
</Entry>

But Entry itself has some context menu like copy etc. by standard. When I did my one. I have removed the original collection.

I am looking for some easy way (instead of redoing standard behaviour) that allows to insert my one context menu item to the standard list of them. Would appreciate any hint.
