Paypal invoice status stays on “DRAFT”

i have got a problem recently trying to make a paypal invoice. well, check this code here.

paypal.invoice.create({
        merchant_info: {
            email: "EMAIL",
            first_name: "FIRST_NAME",
            last_name: "LAST_NAME",
            business_name: "NAME",
            phone: {
                country_code: "CODE",
                national_number: "NUMBER"
            },
            address: {
                line1: "STREET",
                city: "Riyadh",
                state: "Riyadh Province",
                postal_code: "0000",
                country_code: "SA"
            }
        },
        status: "UNPAID",
        billing_info: [{
            "email": "[email protected]"
        }],
        items: [],
        note: `Thank You For Buying`
    })

Ok, i got the invoice made and everything, but the status is “DRAFT”, can someone explain please?
btw i want the status to be “UNPAID”
