I am adding contacts to my hubspot via API. I can add name, email etc via API. But I am stuck on adding notes to the contacts while I add them. Should I pass the notes field in this API call?

This is how I am adding new contacts:

$data = array(
            'properties' => array(
                array(
                    'properties' => 'email',
                    'value' =>  [u_email]
                ),
                array(
                    'properties' => 'firstname',
                    'value' => [u_fullname]
                ),
                array(
                    'properties' => 'lastname',
                    'value' =>  ''
                ),
                array(
                    'properties' => 'phone',
                    'value' =>  [u_phone]
                ),
            )
        );

        curl_setopt_array(
            $curl,
            array(
                CURLOPT_URL => "https://api.hubapi.com/contacts/v1/contact?hapikey=" . $hubspot_key,
                CURLOPT_RETURNTRANSFER => true,
                CURLOPT_ENCODING => "",
                CURLOPT_MAXREDIRS => 10,
                CURLOPT_TIMEOUT => 0,
                CURLOPT_FOLLOWLOCATION => true,
                CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
                CURLOPT_CUSTOMREQUEST => "POST",
                CURLOPT_POSTFIELDS => json_encode($data),
                CURLOPT_HTTPHEADER => array(
                    "Content-Type: application/json"
                ),
            )
        );

The notes field that I am trying to mention can be seen in the screenshot here – https://prnt.sc/u3miov

Any help would be more than appreciable.

Thank you.
