Creating new Subpanel in custom module

Hello guys,

I would like to add a new subpanel to my custom module but this is the result :

I created the vardefs definition :

$dictionary["Document"]["fields"]["cde_individus_documents_1_name"] = array (
  'name' => 'cde_individus_documents_1_name',
  'type' => 'relate',
  'source' => 'non-db',
  'vname' => 'LBL_CDE_INDIVIDUS_DOCUMENTS_1_FROM_CDE_INDIVIDUS_TITLE',
  'save' => true,
  'id_name' => 'cde_individus_documents_1cde_individus_ida',
  'link' => 'cde_individus_documents_1',
  'table' => 'cde_individus',
  'module' => 'CDE_INDIVIDUS',
  'rname' => 'name',
);

I created the layout definition :

<?php
 // created: 2019-03-05 14:18:08
$layout_defs["CDE_INDIVIDUS"]["subpanel_setup"]['cde_individus_documents_1'] = array (
  'order' => 100,
  'module' => 'Documents',
  'subpanel_name' => 'default',
  'sort_order' => 'asc',
  'sort_by' => 'id',
  'title_key' => 'LBL_CDE_INDIVIDUS_DOCUMENTS_FROM_DOCUMENTS_TITLE',
  'get_subpanel_data' => 'cde_individus_documents_1',
  'top_buttons' => 
  array (
    0 => 
    array (
      'widget_class' => 'SubPanelTopButtonQuickCreate',
    ),
    1 => 
    array (
      'widget_class' => 'SubPanelTopSelectButton',
      'mode' => 'MultiSelect',
    ),
  ),
);

And I added the custom LBL in the language file.
I declared all these files in the manifest.php file but I can’t see my subpanel in my module.

I hope someone can help me.
thank you in advance !
