AppIntent Parameter Argument List of Apps

I found the solution, with an EntityQuery you can achieve the expected result. The con is that you actually need to have a list of Apps for it to work. Here is the code:

Step 1: Create an AppEntity

struct EntityName: AppEntity, Identifiable {
  var id = UUID()
  let url: String
  let name: String

  var displayRepresentation: DisplayRepresentation {
    DisplayRepresentation(title: "\(name)")
  }

  static var typeDisplayRepresentation: TypeDisplayRepresentation = "App"
  static var defaultQuery = AppQuery()
}

Step 2: Create AppQuery

struct AppQuery: EntityQuery, EntityStringQuery {
  func entities(for identifiers: [UUID]) async throws -> [EntityName] {
    identifiers.compactMap { id in
      apps.first { $0.id == id }
    }
  }

  func entities(matching string: String) async throws -> [EntityName] {
    return apps.filter { $0.name.localizedCaseInsensitiveContains(string) }
  }

  func suggestedEntities() async throws -> [EntityName] {
    // assuming you defined apps somewhere
    return apps
  }
}

Step 3: Use Entity in AppIntent

struct SomeIntent: AppIntent {
  static let title: LocalizedStringResource = .init("T", defaultValue: "Some Name")
  static var openAppWhenRun: Bool = false

  @Parameter(title: "Select App Here!")
  var selectedApp: EntityName

  @MainActor
  func perform() async throws -> some IntentResult & OpensIntent {
      // handle
  }
}

Hope, this may help someone!
