Unable to load Additional Checkout Buttons in Cart Drawer

Hello,

I have been trying to add accelerated checkout options (e.g. ShopPay) to our cart drawer, but they don’t seem to be showing up. We have enabled them in our Admin settings because the ShopPay option is showing up in the product pages. The dev documentation says to insert the following code:

{% if additional_checkout_buttons %}
  {{ content_for_additional_checkout_buttons }}
{% endif %}

This doesn’t produce anything, and when checking the value of ‘additional_checkout_buttons’, it returns false, even on product pages where it is showing an additional checkout button. I would appreciate any insight on how to proceed in this situation.

Also in the theme editor customization, additional checkout buttons are enabled (though that’s only an option for product pages, not under the cart section). Additionally, we are using the Dawn Theme.
