I'm not able to display user data in email template

I’m trying to display this code in the passwordless email template

 <strong>{{ application.name }}</strong>
              <strong>{{ user.name }}</strong>
              <strong>{{ user.user_metadata.exam_link }}</strong>
              {% for item in user %}
							  {{ item[0] }}: {{ item[1] }}
							{% endfor %}

But for some reason is not displaying all the user fields available (I want user name & metadata), is just displaying this fields: email, source_ip, country, city, application name

I saw in the docs that user object is full available for customized emails

What am I doing wrong??
