Widget not updated when selecting AppEnum with AppIntents

Hello, I'm new here so I apologize if this is obvious, but I can't seem to figure it out and I couldn't find anything online.

I'm trying to select options for a widget using a drop-down, and provide the user with a limited list of options that will never change. I'm using an AppEnum as recommended. However, when selecting an element from the back of the widget, the widget doesn't update.

Here's my code:

import AppIntents
import SwiftUI
import WidgetKit

struct TestProvider: AppIntentTimelineProvider {
	func placeholder(in context: Context) -> TestEntry {
		TestEntry(date: .now, bool: false, str: "Apple", enum1: TestEnum.test1)
	}
	
	func snapshot(for configuration: TestIntent, in context: Context) async -> TestEntry {
		return TestEntry(date: .now, bool: false, str: "Apple", enum1: TestEnum.test1)
	}
	
	func timeline(for configuration: TestIntent, in context: Context) async -> Timeline<TestEntry> {
		let testBool = configuration.bool
		let testStr = configuration.str

		return Timeline(entries: [
			TestEntry(
				date: .now,
				bool: testBool,
				str: testStr,
				enum1: TestEnum.test1
			)
		], policy: .atEnd)
	}
}

struct TestEntry: TimelineEntry {
	let date: Date
	let bool: Bool
	let str: String
	let enum1: TestEnum
}

struct TestIntent: AppIntent, WidgetConfigurationIntent {
	static var title: LocalizedStringResource = "Testing"
	static var description: IntentDescription = .init(stringLiteral: "1, 2, 3, testing")

	@Parameter(title: "Test bool")
	var bool: Bool

	@Parameter(title: "Test string", default: "Apple")
	var str: String

	@Parameter(title: "Test enum", default: .test1)
	var tenum: TestEnum
}

struct TestWidgetView: View {
	var entry: TestEntry

	var body: some View {
		VStack {
			Text(entry.str)
				.foregroundStyle(entry.bool ? .green : .red)
			Text(entry.enum1 == TestEnum.test1 ? "1" : "2")
			Text(entry.enum1.rawValue)
		}
		.containerBackground(for: .widget) {}
	}
}

struct testWidget: Widget {
	let kind: String = "Test Widget"
	
	var body: some WidgetConfiguration {
		AppIntentConfiguration(kind: kind, intent: TestIntent.self, provider: TestProvider()) { entry in
			TestWidgetView(entry: entry)
		}
		.configurationDisplayName("Test widget")
		.description("Just a test")
		.supportedFamilies([.systemSmall])
	}
}

enum TestEnum: String, AppEnum {
	static var typeDisplayRepresentation: TypeDisplayRepresentation = "Test title 1"

	case test1 = "1"
	case test2 = "2"

	static var caseDisplayRepresentations: [TestEnum : DisplayRepresentation] = [
		.test1: "test 1",
		.test2: "test 2"
	]
}

#Preview(as: .systemSmall) {
	testWidget()
} timeline: {
	TestEntry(date: .now, bool: false, str: "Apple", enum1: TestEnum.test1)
}

It's a pretty simple example. The widget updates correctly if I change the boolean or the string, but not if I change the enum selection.

What am I doing wrong?

Many thanks in advance for the help.
