Retrieve chat log during game

I am trying to develop an application that needs to retrieve the ingame chat during your own game.
This can’t be done by storing my own inputs because I want to retrieve game chat from all players in my team (so just the team chat).
I have tried to use tesseract to read the text from an image but this doesn’t retrieve the correct text. It does not recognize all the characters or only recognizes parts of a sentence/word.
Is there a way to retrieve the chat messages or correctly get the exact text from an image?
