Hello, I am creating custom DX component and i have problem with it. I am trying to render plus and trash icons as stated at design.pega.com, yet they render only in StoryBook (in web portal they are missing). Here is part of the code:  

import { Flex, DateRangeInput, Button, Icon, Card } from '@pega/cosmos-react-core';
.....                   
                    <Button
                      variant='simple'
                      label='Icon button link'
                      icon
                      aria-label='remove'
                    ....
                    >
                      <Icon name='trash' className='trash-icon' />
                    </Button>
...

Icon does not render here as in any other component that i have created. Can you please advise if i am missing any dependency?
