Adds an item to a collection.
An item can only be inserted into an existing connection. You can create a new collection using the Data Collections API.
When an item is inserted into a collection, the item's ID is automatically assigned a random value.
You can optionally provide a custom ID in dataItem.id when inserting the item.
If you specify an ID that already exists in the collection, the insertion will fail.
If options.dataItem.data is empty, a new item is created with no data fields.
You can only call this method when authenticated as a Wix app or Wix user identity.
