Max_history is used to define how much of your past conversation needs attention. If your conversation is longer and the bot needs to remember details from different parts of the conversation, set this parameter to a higher value.
In your case, “max_history : 3” will work fine as the bot only needs to know “anythingelse_value” from previous step. You can use 3 or 5 for this case.
