You need to use Destinations to collect the new quest data. Inside Destinations settings you need to enable the collecting of quest data first in order to save new found quests to the SavedVariables of Destinations.
After you found new quests you need to run this tool to get the collected quest data from the SavedVariables and then provide these to the author.

He needs to update the data into destinations internal tables then.
As SnowmanDK is not active anymore as it seems I guess send data was just not updated (if any was still sent).
In the end this takes a lof of time and I'm pretty sure noone is doing this anymore because of this reason
But I also ask myself: Whatfor do I need to see the quests on the maps?
If I run around, I find them as well. And there are websites having nearly all quest data as well (UESP e.g. and others) where you can have a look. It takes time, yeah, same problem here
Btw.
I think QuestMap works the same only that the author himself maybe collected the data and did not let the users collect them. This is only a guess as I'm not aware of any ingame API functions to collect all quests of a zone AND their positions on the map!
