Welcome to Seller Community, @yasmeensoomal.
If you don't see those as options in the list of icons then there wouldn't be a way to add them right now. You might be able to add a third party widget to the site instead. If it uses a solution where you just need to add code to the header code area, then you can add that by going to Website > Integrations and adding a header code.
