How do I replicate the drop-down toolbaritem “more” in xamarin.forms?

I am struggling how I could replicate the drop-down ToolbarItem from Xamarin.Forms when a ToolbarItem's order is set to Secondary for IOS, in order for it to look like it does for Android.

What I have tried:

How it works in Android:
Code:

ToolbarItem toolbarItem = new ToolbarItem()
{
  Text = "ToolbarItem",
  Order = ToolbarItemOrder.Secondary
};

Screenshots:
Image showing the more icon
Image showing the expanded more icon
Image showing an example of how it has been achieved already in IOS

There is no default "More" icon on the toolbar when setting the Order to Secondary in iOS. Instead what happens, is that a bar below the navigation bar is created, which includes all of the toolbar items - something I do not wish to have for my Application.

Thank you so very much for taking the time out of your day to read my question, and I appreciate any feedback that you may have.

Kind regards,
Daniel
