    • Sets the colors to apply to NowVoice UI elements.

    To match the voice UI to your app's visual identity, create a type conforming to NowVoiceThemeable and pass it to NowVoiceService - startVoice(endpoint:uiConfiguration:callbacks:theme:) or NowVoiceService - updateTheme(theme:).

    import NowVoice

let instanceUrl = URL(string: "https://your-instance.service-now.com")!

do {
    let voiceService = try await NowVoice.makeVoiceService(instanceUrl: instanceUrl)
} catch {
    // Handle NowServiceError (see Error reference below)
    print("Failed to create voice service: \(error)")
}

struct MyVoiceTheme: NowVoiceThemeable {
    var color: NowUIColoring = MyAppColors()
}

// Apply at voice session launch
let vc = try await voiceService.startVoice(endpoint: endpoint, theme: MyVoiceTheme())

// Or update while a voice session is active
voiceService.updateTheme(theme: MyVoiceTheme())
