Currently we have a cli config settings called autoOpenBrowserOnLogin which if value is true will open the browser window automatically.
Now we have introduced a new generic settings config called autoOpenLinksInBrowser as per issue #3118 , we will have to

• Remove the config settings autoOpenBrowserOnLogin
• Make the change in the m365 login so that it respects the config settings autoOpenLinksInBrowser rather than the settings autoOpenBrowserOnLogin
• Remove the old settings autoOpenBrowserOnLogin

Since this is a breaking change, we will be introducing the change only in V6.
