How to get custom attribute (accessors)

[MxFlorin]

I have:

public function getAddressAttribute()
    {
        return $this->address_line_1 . ', ' . $this->address_line_2 . ($this->address_line_2 ? ',  ' : '') . $this->city . ', State: ' . $this->state_or_region . ', Postal Code: ' . $this->postal_code . ', Country: ' . $this->country_code;
    }

and in export columns I have

$exportColumns = [
                'order_id'    => 'Order Number',
                'order_date'  => 'Order Date',
                'channel'     => 'Channel Name',
                'merchant_id' => 'Chanel ID',
                'name'        => 'Customer Name',
                'qty'         => 'Qty',
                'skus'        => 'SKUs',
                'address'     => 'Address',
            ];

But the address is not populated. How can I get accessors? Thanks in advance.
