Hi Folks - I am using JANSSON to store JSON data in an htable.  How does one remove an entire element from a JSON?

I do not see a specific function mentioning clear or remove exposed in the Kamailio module, but do see various clear/remove methods in the underlying C library. 

Below does set the value of key foo to null.  I would like to remove both the key and value of foo. 

jansson_set("null", "$var(foo)", "$var(json)", "$var(result)");


Running Kamailio v5.4
Debian 10
