How do i use the stream deck to send messages in game?

Ive tried the multi action way and the plugin from the raider person,neither wok? is there an actual way to use the stream deck to send messages in game? setting the hotkey as enter,and then following with the chosen text doesnt work, is it just not possible for games? the function works for discord and regular programs but when it comes to games it just doesnt work am i missing something or has anyone else gotten this to work in there games that have text chats in them?
