No, I only request a "Manual Text" option in Chat Messages Filter. (Auto Text but it enters the text in chat for you to enter it or not.)

Look for chat filtering or message handling code in the Minecraft mod, likely in UI components for chat. The issue lacks specifics on what 'Manual Text' means or where to add it. Start by exploring the mod's chat message filter feature to understand the current 'Auto Text' implementation and identify where a manual option could be integrated.
