#       "sub_roles": [
#         "Tech",

#       ],
#       "viewable_for_sharing": true,
#       "eula_create_date": 1649108951523
#     }
#   ]
# }

# The destination is the empty "users" array, the source is the populated "users" array in jsonB.

# Copy the array items from source to dest
CkJsonArray_AppendArrayItems $jsonUsersDest $jsonUsersSrc

puts [CkJsonObject_emit $jsonA]

# The end result is this:

# {
#   "ciphertext": "encryptedData",
#   "status": 200,
#   "error": "errorMsg",
#   "users": [
#     {
#       "role": "Surgeon",
