How to finish it?

The codes in OpenWebRTCNativeHandler

static void got_candidate(GObject *media_session, OwrCandidate *candidate, gpointer user_data)
{
NSLog(@">>>>>>>>>>>>>>>>>>>>>>>>>> Got local candidate");
GList *local_candidates;
g_return_if_fail(!user_data);

```
local_candidates = g_object_get_data(media_session, "local-candidates");
local_candidates = g_list_append(local_candidates, candidate);
g_object_set_data(media_session, "local-candidates", local_candidates);

if (staticSelf.delegate) {
[staticSelf.delegate candidateGenerate:@""];
// TODO: Send candidates.
NSLog(@"############################# TODO: Send candidate to other side (ICE trickle).");
}
```

}
Can you tell me how to send candidate to other side please? Thank you!!
