Removing the space above the searchable search bar in navigation view in SwiftUI

Question

I am testing out the SwiftUI's feature .searchable(). But seems that the search bar would always has a space above it. Since the searchable is embedded in the naviagation bar, I understand the space as where the Navigation bar items go. But is there a way to remove that space and make the searchbar looking like that in Instagram? I have tried changing the navbar style to inline,as the code below, but there is still some space above it. Is there any logic behind the search bar's position?

NavigationView{
    SearchView(searchText: $searchText)
        .navigationBarTitleDisplayMode(.inline) 
}
.searchable(text: $searchText, placement: .navigationBarDrawer(displayMode: .always), suggestions: {
    ForEach(searchResults, id: \.self){result in
        Text(result).searchCompletion(result)
        
    }
})
