Hello @Maviakhan,
Have you tried using your TV remote to see if you can advance the setup? Some TVs support a connection where the Chromecast can be controlled from the remote.
If you have an Android device, you can try activating Google Assistant and say, "set up my device." It should then connect to your device and help you set it up.f
If these methods don't work and you are still not able to connect to your Chromecast you can order a replacement Voice Remote.
Let me know if you have further questions.
