I am trying to insert an icon to my coreUI template from one of these -

However, i get this error -

I did -

  npm install @coreui/icons --save

and added 'icon-cog' in nav.ts

     {

      name: 'API Venn ',

      url: '/api-venn',

      icon: 'icon-cog',

      children: [

        {

          name: 'Relationship based Venn',

          url: '/api-venn/relationvenn',

          icon: 'icon-puzzle'

        },

        {

          name: 'Node based Venn',

          url: '/api-venn/nodevenn',

          icon: 'icon-puzzle'

        }]

      },
