Use page.find with list fields?

Is it possible to use page.find in a list output because having no joy?

This outputs as expected {{ page.find(’/mypage’).header.tagline }}

but I can’t get it to work here…

    {% for list_page in page.header.list_page %} {% set page = list_page.folder %} ---> where folder is the url /mypage {% set ptag = page.find('page').header.tagline %}
  • {{ ptag }}
  • {% endfor %}

Tried
{% set ptag = page.find(‘page’).header.tagline %}
{% set ptag = page.find(’{{ page }}’).header.tagline %}
