trying out firestore rest, the documentation states that to order items ?orderBy=name%20desc
this orders using the document name in descending order. The documents I need to order have the following structure
{"name": "document_name","fields":{"createTime": "2024-08-23T23:06:05.206209Z", }}
how could I order using the createTime field? since doing ?orderBy=fields.createTime
returns empty json
