How to 'Stealth Mode'

Hi!(๑╹◡╹๑)
How to Stealth Mode in ourWorld?

First is click your 'Account' and click the 'Settings'

And now you're in your settings..

Look at the 'Communication' there's "Show my friends I am online (?)" and options <Yes><No>
and click the (?) Sign to learn more.

And now this is looks like after choosing the <No> option, now your friends can't see you're online!~

Hope you guys get it!
Done~
