Mongoose search for items on array containing _id with aggregate

Question

For example, i have a document like this

{
    _id: 1,
    name: "example name" 
}, 
{
    _id: 2,
    name: "example name 2" 
},

I wound like to pass an array with ids, example: [1, 2], and receive back these documents selected within aggregation mongoose method
