How use icons fontawesome?

How I can insert on nav icons of fontawesome.
I have many icons (200 icons on my BD)
I try

let rutas [
    {
      _tag: 'CSidebarNavItem',
      name: 'Users',
      to: '/users',
      icon: 'fas fa-users',
      badge: {
        color: 'info',
        text: 'NEW',
      }
    },
    {
      _tag: 'CSidebarNavItem',
      name: 'Sales',
      to: '/sales',
      icon: 'cil-users',
      badge: {
        color: 'info',
        text: 'NEW',
      }
    }
  ]

< CCreateElement
          items={rutas}
          components={{
            CSidebarNavDivider,
            CSidebarNavDropdown,
            CSidebarNavItem,
            CSidebarNavTitle
          }
          }
        />

Olso I try whit fontIcon: ‘fa fa-book’ , but return same error.

but return error:

CIcon component: icon name 'faUsers' does not exist in React.icons object. To use icons by 'name' prop you need to make them available globally by adding them to React.icons object.

CIcon component: icon name 'fas faUsers' does not exist in React.icons object. To use icons by 'name' prop you need to make them available globally by adding them to React.icons object. CIcon component docs: https://coreui.io/react/docs/components/CIcon

any solution?? for use dinamic

Use fontIcon prop instead:

let rutas [
{
  _tag: 'CSidebarNavItem',
  name: 'Users',
  to: '/users',
  fontIcon: 'fas fa-users',
},
