MongoDB : given an array of objects, update the ones that are existing or add if it is not existing

I have an array of objects that looks like this:

[
    {
        customer_id: "A100",
        status: "purchased",
        order_price: 30,
    },
    {
        customer_id: "A102",
        status: "in cart",
        order_price: 50,
    },
    {
        customer_id: "A103",
        status: "in cart",
        order_price: 60,
    },
    {
        customer_id: "A102",
        status: "purchased",
        order_price: 70,
    }
]

I want to update the documents in my database based on the customer_id, such that if any document with customer_id of A100 or A102 etc is existing it should update it, and if not it should add it.

Assume my database has the following documents:

[
    {
        customer_id: "A100",
        status: "in cart",
        order_price: 30,
    },
    {
        customer_id: "A102",
        status: "viewing",
        order_price: 20,
    },
    {
        customer_id: "B100",
        status: "purchased",
        order_price: 100
    }
]

after the operation, my database should look like this

[
    {
        customer_id: "A100",
        status: "purchased",
        order_price: 30,
    },
    {
        customer_id: "A102",
        status: "in cart",
        order_price: 50,
    },
    {
        customer_id: "A103",
        status: "in cart",
        order_price: 60,
    },
    {
        customer_id: "A102",
        status: "purchased",
        order_price: 70,
    },
    {
        customer_id: "B100",
        status: "purchased",
        order_price: 100
    }
]

NOTE : the document with customer_id: "B100" is still left untouched
