Chat in the DGT app

Played another game on Lichess today but again I could not see how to chat with the player during the game. 

Am I missing something? A little frustrating that I cannot greet the other player nor offer GG afterwards.  

I don't think there's a way. However, Lichess does have an option in the settings (under Game Behavior) to "Say "Good game, well played" upon defeat or draw" automatically. That's the only alternative I know of.

How do you access "Game Behavior" settings?

On the Lichess website - click on your username in the top right of the page, click "Preferences", then Game Behavior is third option down. 

Thanks Rsava.
