retrieve_multiple(
entity:'contact', 
select:["fullname","ownerid"], 
filter: {"contactid":"ae8bca63-706a-ed11-9561-000d3a227751"},
order: {"fullname":"desc"}, 
expand:"ownerid",
top:2,
includeCount: null,

) %}

<ul>
{% for record in records %}
    <li> <b>Name: </b>{{record["fullname"]}}|{{record["ownerid"].Name}}</li>

guid: 'fa7eadd1-f343-ed11-bba2-6045bd8e5463',
select:["accountid","name","ownerid"], 
expand:"ownerid"
)

<li><b>ID:</b> {{record1["accountid"]}} <b>Name: </b>{{record1["name"]}} |{{record1["ownerid"].Name}}</li>

{% set recordRef = recordOne|to_entity_reference %}
