cutChatCache how should you use, what do you receive

cutChatCache how should you use, what do you receive.
cutChatCache(): Promise<{ after: { chats: number ; msgs: number } ; before: { chats: number ; msgs: number } }>

What should I specify in after: { chats: number ; msgs: number }
What should I specify in before: { chats: number ; msgs: number }

I understand that the purpose of this function is to reduce the amount of chat and messages in the cache
