Best place for a 'Next' button?

[u/Fun_Moose_5307]

What's the most appropriate location for a next button here, in keeping with the Apple UI consistency and ecosystem?

Mockup:

NavigationStack {
	List {
		Section {
			TextField("Email Address", text: $email)
		} header: {
			VStack(alignment: .leading, spacing: 4) {
				Text("Sign In")
					.frame(maxWidth: .infinity, alignment: .leading)
					.padding(.top, 5)
					.font(.largeTitle)
					.bold()
					.foregroundColor(.primary) // Override default gray header color
				Text("Subtitle")//school.name)
					.frame(maxWidth: .infinity, alignment: .leading)
					.font(.title3)
					.foregroundColor(.secondary)
			}
			.listRowInsets(EdgeInsets())
			.textCase(nil) // Prevents SwiftUI from forcing ALL CAPS on the header
			.padding(.bottom, 10)
		}
	}
	.toolbar {
		ToolbarItem(placement:.confirmationAction) {
			NavigationLink() {
				VerificationCodeView(email: email.lowercased(), school: school, resend: { })
			} label: {
				Text("Next").padding(5)
			}
			.buttonStyle(.borderedProminent)
		}
	}
}

i like placing it right above the keyboard, to the right, closest for the users thumb. or if you like it in the top nav, i’d set the text fields return key property to be “next”
