You could use this dev doc to register those fields with Connections so they can be exported:

https://connections-pro.com/quicktip-custom-field-adding-a-text-field/#Export_the_Field

Something like this should work:

// Register the custom test field CSV Export attributes and processing callback.
add_filter( 'cn_csv_export_fields', 'cn_register_text_field_header' );
add_filter( 'cn_csv_export_fields_config', 'cn_register_text_field_config' );

function cn_register_text_field_header( $fields ) {

  // The field_id should match exactly the field id used when registering the custom field.
  $fields['Branch Logo']     = 'Branch Logo';
  $fields['Marker Location'] = 'Marker Location';

  return $fields;
}

function cn_register_text_field_config( $fields ) {

  $fields[] = array(
    'field'  => 'Branch Logo', // The field_id should match exactly the field id used when registering the custom field.
    'type'   => 5,
    'fields' => '',
    'table'  => CN_ENTRY_TABLE_META,
    'types'  => NULL,
  );

  $fields[] = array(
    'field'  => 'Marker Location', // The field_id should match exactly the field id used when registering the custom field.
    'type'   => 5,
    'fields' => '',
    'table'  => CN_ENTRY_TABLE_META,
    'types'  => NULL,
  );

  return $fields;
}

Hope this helps!
