How can i return a subquery as a object?

SQL++
1

i have the below query that gets me the data of my users nd the info for there last login which is stored in my security login_history array. All works as expected, the only thing i like to change is instead of having all item of lh returned on same level as the main object, i would like to create a object called history and then have all keys of lh returned under that.

SELECT META(c).id,
       c.username,
       c.name.fname,
       c.name.lname,
       c.security.admin,
       c.security.password_expiration,
       c.security.developer,
       c.security.locked,
       lh.*
FROM Contacts c
LET lh = (
    SELECT h.*
    FROM c.security.login_history AS h
    ORDER BY h.date DESC
    LIMIT 1)[0]
WHERE c._type = "user"

When i try to use 
`OBJECT_ADD( lh,"day_new", 1) AS history`

it forces me to also add key and key value which i don’t want to do…

    ORDER BY h.date DESC
    LIMIT 1)[0]
WHERE c._type = "user"

Thank, so simple … what caused my issue as i tried original the lh.* as history which threw an error and there is no reference on the docs under Object for this simple basic solution
