Publish Fortnite Map?

I wanted to publish my map now the problem is there: Must contain at least 1 day (s) to publish, maybe someone knows exactly what it means or what you have to enter there?

You need a creator code to publish a map

With tags such things are meant:

You have to write in individual words describing your map. Such as. Deathrun, Escape Room, etc.

I've already tried it but it doesn't work, maybe I'm doing something wrong?

Try a comma after every word. It's the same with YouTube
