How do I set the tint of additionalOverflowItems More Button in iPhone Landscape (for Duo)

I am taking the advice in https://developer.apple.com/videos/play/tech-talks/111462/

And using (in Obj C) navigationItem.additionalOverflowItems = UIDeferredMenuElement({ provider in provider(self.persistentOverflowItems()) })

This is quite fine as I already had menus on my barButtons.

But the overflow menu doesn't match my color palette. It is white, and nothing else onscreen is. White = 100% on and draws the eye, whereas overflow should be the least important item on the screen. Thus, I should be able to color it. But with Glass, we can't set the bar tint and have it do anything useful. I can set the tint color of a .backItem.

But I do not see a .overflowItem to set the TintColor of.

I will be tempted to not use the system Overflow (as suggested in the video and there's usually an unspoken reason for so I'd like to use the system one, just not in white), and instead favor my own More button.

Am I missing something or do I need to write a feedback?

In addition, if I use a bar button that I've added as a uiaction as an element in this menu (for items that don't have menus as their action), and want to use the bar button as the zoom animation source view, it doesn't work. Obviously. How do I set the overflow menu as the zoom source in this instance?
