Run forminator_custom_form_submit_errors hook only for submit?

Hi there,
So, I am using forminator_custom_form_submit_errors hook to send the form data to a custom endpoint. But, I just realized it also run when user click on Save Draft button. Is there a way to prevent this? I just want to run the function when user click the submit button. Here’s the sample code.

/**
 * Send the form data to API
 */
add_action(
    'forminator_custom_form_submit_errors',
    function ($submit_errors, $form_id, $field_data_array) {
        if ($form_id != FORMID) {
            return $submit_errors;
        }

        // API key & Endpoint
        $endpoint = 'ENDPOINT_URL';

        // Form data
        $data = array_column($field_data_array, 'value', 'name');

        $body = [
            'name' => $data['text-1'] ? esc_attr($data['text-1']) : '',
        ];

        // JSON encode data
        $body = wp_json_encode($body);

        // Send the data to the API
        $response = wp_remote_post($endpoint, [
            'body'        => $body,
            'headers'     => [
                'Content-Type' => 'application/json',
            ],
            'timeout'     => 60,
            'redirection' => 5,
            'blocking'    => true,
            'httpversion' => '1.0',
            'data_format' => 'body',
        ]);

        if ($response['response']['code'] !== 200) {
            $submit_errors[]['submit'] = 'API Error!';
            $GLOBALS['api_error'] = true; // for custom message.
        } else {
            $GLOBALS['api_error'] = false;
        }

        return $submit_errors;
    },
    15,
    3
);

Thank you.
