title: Odoo Missing Dependencies: web.ControlPanelMixin
body: <p>I'm trying to install some module In Odoo 13 Community. The dependency <code>'web.ControlPanelMixin'</code> is missing, I'm trying to fing the problem, so far I got no succes.
  The JavaScript Code:</p>
  
  <pre><code>odoo.define('crm_dashboard.dashboard', [
    'web.core',
    'web.framework',
    'web.session',
    'web.ajax',
    'web.ActionManager',
    'web.view_registry',
    'web.Widget',
    'web.AbstractAction',
    'web.ControlPanelMixin'
  ], function (require) {
    "use strict";
    var core = require('web.core');
    var framework = require('web.framework');
    var session = require('web.session');
    var ajax = require('web.ajax');
    var ActionManager = require('web.ActionManager');
    var view_registry = require('web.view_registry');
    var Widget = require('web.Widget');
    var AbstractAction = require('web.AbstractAction');
    var ControlPanelMixin = require('web.ControlPanelMixin');
    var QWeb = core.qweb;
    ...
  });
  </code></pre>

  ./doc/reference/javascript_reference.rst:2224:        var ClientAction = AbstractAction.extend(ControlPanelMixin, {
  ./doc/reference/javascript_reference.rst:2262:- add ControlPanelMixin in the widget:
  ./doc/reference/javascript_reference.rst:2266:        var ControlPanelMixin = require('web.ControlPanelMixin');
  ./doc/reference/javascript_reference.rst:2268:        var MyClientAction = AbstractAction.extend(ControlPanelMixin, {
  ./doc/reference/javascript_reference.rst:2277:        var SomeClientAction = Widget.extend(ControlPanelMixin, {
  ./mymodules/odoo_crm_dashboard/static/src/js/crm_dashboard.js:11:    'odoo.web.ControlPanelMixin'
