    Interface ServiceHandler

    Handler for service-specific messages from napplets. Services receive NIP-5D NappletMessage envelopes and respond via the send callback. The same interface is used for all services regardless of what NAP domain they handle.

    const audioHandler: ServiceHandler = {
      descriptor: { name: 'audio', version: '1.0.0' },
      handleMessage(windowId, message, send) {
        if (message.type === 'inc.emit') {
          // process audio inc event...
          send({ type: 'inc.emit.result', id: (message as any).id });
        }
      },
    };
    interface ServiceHandler {
        descriptor: ServiceDescriptor;
        handleMessage(
            windowId: string,
            message: NappletMessage,
            send: (msg: NappletMessage) => void,
        ): void;
        onWindowDestroyed?(windowId: string): void;
    }
