Issues Integrating Sony TV apps into HomeKit

I am trying to use an app as an input source in HomeKit, so I followed the example in the tutorial at https://www.home-assistant.io/integrations/braviatv and replaced the media_content_id with my own in /homeassistant/automations.yaml.

However, when I open Home, I find that all the original input sources have been renamed to “sony,” and the app I added did not launch.

Does anyone know what the issue could be? How should I resolve this?

It would be helpful to see the actual YAML you have added.
