Javascript Cosmos DB MongoDB API可以'；t调用存储过程/UDF/

伪代码：

const mongoose = require('mongoose');

const { Schema } = mongoose;

const UserSchema = new Schema({
  username: String
});

mongoose.model('User', UserSchema);

const con = mongoose.connect(config.uri, config.options, (err) => {
    if(err) throw err;

    const User = con.model('User');
    User.db.db.command({ testProcedure: 1 }, console.log);
})

错误输出：

存储过程和UDF是本机SQL（DocumentDB）API和相关SDK的方面。MongoDB SDK（或为MongoDB量身定做的框架，如您正在使用的Mongoose）对Cosmos DB的存储过程或UDF一无所知

您需要在特定语言中使用Cosmos DB SDK来利用这些功能。但是，我怀疑它们在使用MongoDB API设置的数据库中是否能正常工作。
您到底想实现什么？@SapuSeven我想在Cosmos DB中执行一个存储过程……正如问题的标题所述。（UDF=用户定义的函数）请参见漂亮的答案。
