WebDriver BiDi Logging Features
These features are related to logging. Because “logging” can refer to so many different things, these methods are made available via a “script” namespace.
Remember that to use WebDriver BiDi, you must enable it in Options. For more details, see Enabling BiDi
Console Message Handlers
Record or take actions on console.log events.
