How to print title of referenced entity using Computed Twig

@jrockowitz Thank you, the twig token worked for calling a single value. I also applied the patch which fixed the twig help. That is really helpful. When using the twig token, is it possible to do the twig for loop when outputting titles for a multi-value reference field? Or maybe I would be better off working with this: {{ data.element_key.delta }}?

OK, I updated to dev and the twig help is working. Thank you. I'm still trying to figure out my question in #4.

...you should be able to loop through multiple values.

Are you saying that I should be able to loop through multiple values of this: {{ webform_token('[webform_submission:values:option:entity:title]', webform_submission) }}? Or were you talking about Twig variables?

Thanks, I'll post once I have the for loop figured out.

Progress report: So far I have these two things working.

I can loop through the entity IDs like this:

<ul>
{% for item in data.choose_opt %}
  <li>{{ item }}</li>
{% endfor %}
</ul>

I can get a specific entity ID like this:
<p>{{ data.choose_opt.0 }}</p>

Still working at making the jump to the entity and its title. This isn't working:
<p>{{ data.choose_opt.0.entity.title }}</p>
nor this
<p>{{ data.choose_opt.0.entity.title.value }}</p>

I'll post when I have anything new.

With some help from markconroy in the Drupal Twig Slack, here is what I did to print the title of entities referenced earlier in the form. I used twig tweak to load a a media entity view mode which I stripped of all its wrappers. Here is the twig markup:

{% set media_ids = data.choose_opt %}
<ul>
{% for media_id in media_ids %}
<li>{{ drupal_entity('media', media_id, 'title_as_string') }}</li>
{% endfor %}
</ul>

1. I set a variable for the entity ID's stored in the choose_opt element.
2. A for loop loops through the resulting array.
3. Twig tweak allows us to load a Drupal entity.
4. I specify the media entity type.
5. My variable media_id passes in the media entity ID.
6. 'title_as_string' is the machine name of a view mode that I've created for the media entity. I needed to remove a couple div wrappers by overriding both the field template and the entity template for this view mode.

Result: On page 1 of the form, user selects several options in an Entity checkboxes element. On page 2 of the wizard, the user sees a summary of what had been selected on page 1. The nice thing is that this method would allow us to load any fields from the referenced entity simply by dragging more fields into the view mode.
