I encountered a problem when using BroadcastChannel in production env seems one of users' browser doesn't support it, so it breaks the code, although I checked it beforehand it doesn't work, and it will pass the condition?

 
  const setBroadcastChannel = () => {
    if (! "BroadcastChannel" in window ) return;
    const bc = new BroadcastChannel(...);
    ...
  }

Apparently, There is another way to install this package but curious if there is a better way to not install a 3rd party package since these users are very few.

Any idea will be appreciated.
