请问这个如何使用啊 how to use this please

[freeoptions]

我在群组中换了好几个头像，然后点击bot的时候还是提示我更换队列为空，可不可以大概介绍一下如何使用，要在哪里设置更换的队列呢

I changed several avatars in the group, and when I clicked on the bot, it still reminded me that the replacement queue was empty. Can you briefly introduce how to use it and where to set the replacement queue?

thank you ！
