Displaying inline SVG Image field in Twig template

It is not common to have third and fourth level entity references all immediately loaded for rendering in Twig.

This functionality can best be achieved using the drupal_entity function provided by the Twig Tweak → module, which is one of the primary reasons that module exists.

{% set file_url = paragraph.field_image_text_content_ref.entity.field_svg_image | file_url %}
Inline SVG: {{ source(svg_url) }}
IMG Tag:<img src="{{ svg_url }}" />

Closing this as works as designed.
