My goal is to add a Fontawesome icon inside a submit button using simple\_form\_for

[Final goal](https://i.stack.imgur.com/O8Rxa.png)

right now the form is like:

```
            <%= simple_form_for @model, html: {class: "d-flex align-items-end"} do |f| %>
            <%= f.input :model, :as => :hidden, :input_html => { :value => model.id } %>
            <%= f.input :x, label: false, :input_html => { :value => model.x_attr } %>
            <%= f.button :submit, "x", class: "btn btn-secondary" %>
            <% end %>

```

And form is:

Is it possible to add a 
`<i class="fas fa-cart-arrow-down"></i>`
inside that button with simple\_form?
