bsl::unordered_map<basic_string<char>, Json, TransparentHash, TransparentEqualTo>::insert_or_assign

If a key equivalent to the specified key already exists in this unordered_map, assign the specified obj to the value associated with that key, and return an iterator referring to the existing item. Otherwise, insert into this map a newly-created value_type object, constructed from (std::forward<KEY>(key), std::forward<BDE_OTHER_TYPE>(obj)...)), and return an iterator referring to the newly-created entry. Use the specified hint as a starting point for checking to see if the key already in the unordered_map.
