How do you use "is defined" in a script? (lemmy.world)

I'm trying to get a script built. I want to check if a variable exist and include it if it does. Just really struggling to figure out the formatting. Something like

script:
  sequence:
    target:
      entity_id: "{{ entity }}"
    {% if variable is defined %}
      data: "{{ variable }}"
    {% endif %}

It worked the same as your suggestion above. In cases the variable is used it does works as intended but in the situation the variable is not set it's still sending data: just with a blank value.
