Fortnite: How to find and join a specific Creative Mode map?

In Fortnite there was a map I was playing on for a while called BHE 1v1 Build Fights that was really good for practicing. Since one can easily die quickly in a build fight, and it takes maybe 20 minutes of collecting items and powering up leading up to such a showdown, a practice map is really the only way to get better.

This map was perfect for this, offering unlimited lives, ammo, and building supplies, to face off against other players building and shooting non-stop. But now I can't find it because the Creative Mode lobby area (or whatever it's called) changes frequently.

The whole navigation schema for finding a Creative Mode map is a cluster screw, since one has to fumble around a purely decorative 3D environment to navigate to a map (looks pretty, but gets annoying fast). Still, one would at least expect there to be a way to join a user-hosted map using a code or bookmark system or something. There was a code that was displayed at the top of the screen while playing: BHE 8064-****-**** I'm not sure if it's a public code for joining, or something specific to me (hence the asterisks).

Can I use that code to look up that map or server, and join? Or is there any way of finding that awesome practice map again?

go to one of the portals in creative and interact with one of the consoles next to the portals. there is a tab there called recent. go to that and you should find. if that doesn't work, search for 1v1 BHE creative codes in the internet. once you get a code, enter it in the code tab and you can play it. if you find a cool creative like this that you like, make sure to mark it as favourite so that you can easily use it any time (its like saving it).
