Search Bar Left Image Tint Change iOS for Dark Mode

Question

Trying to get the left most image icon within the search bar to change color for Dark Mode in iOS 13

Ive tried making a call directly to the searchBar and changing its background color, changing the text color, and finally I've tried a couple different iterations of the code below.

        searchBar.backgroundColor = .clear
        searchBar.backgroundImage = UIImage(named: "magnifyingglass")
        if #available(iOS 13, *) {
            searchBar.textField?.attributedPlaceholder = 
    NSAttributedString(string: (" " + NSLocalizedString("search_actions", comment: "")), 
    attributes: [NSAttributedString.Key.foregroundColor: UIColor.separator, 
    NSAttributedString.Key.strokeColor: UIColor.separator])
            
        }
