discord.py机器人重启后如何实现历史事件日志记录？

我正在为Discord机器人开发日志系统，当前系统仅能记录机器人启动后的事件，若机器人重启，重启前的历史消息与事件无法被记录，这是核心问题。现寻求解决方法，使机器人重启后仍能处理历史事件的日志记录。

以下是日志发送的完整代码：

@bot.event
async def on_member_remove(member):
                with open("database\database_main\serverdb.json", encoding="utf-8") as f:
                    data = json.load(f)
                if str(member.guild.id) in data:
                    logera = data[str(member.guild.id)]['log_leavelogs']
                    if logera == 0:
                        with open("database\database_main\serverdb.json", encoding="utf-8") as f:
                            data = json.load(f)
                        if str(member.guild.id) in data:
                            isenabled = data[str(member.guild.id)]['logchlID']
                            if isenabled == 0:
