How to render formatted phone_number in Twig

I have an entity with an entity reference to another entity that has a phone_number field. I am trying to display the formatted phone number in the first entity's template, but I can't seem to get the formatting.

Here is how I am accessing the phone number:

{{ content.field_entity_reference.entity.field_phone_number }}

This throws a Twig error.

I entered the phone number in this format +1 (ddd) ddd-dddd, which is how I would like to display the phone number, but I can't figure out how to get my formatting back out of the field.

field_phone_number.0 has these keys:

• value
• country
• local_number
• extension

field_phone_number.0.value just returns +1dddddddddd, without any formatting.

So, what I am wondering is there an easy way to get the formatting at the theme layer? Do I need to use the phone_number.util service?
