Please fix the Chrome Cast button on the YouTube app. I keep accidentally hitting it bec it's right next to the other buttons and without a warning or confirm button it streams out to the main TV or even someone else's device, just disturbing everyone.
While there isn't such option available. Also, we'd recommend sending us a feedback directly from your YouTube account reporting the issue with these steps: https://yt.be/help/RYwc . You may not get a direct response, but we do review everything to investigate and fix issues.
