Problem bridging eth from mainnet to nova

Hi, as the title says, I'm having trouble bridging my ethereum from the mainnet to arbitrum nova in metamask. I have eth on mainnet and my moons on nova. When I go to the bridge in app, I can select ethereum as the start network, and the amount. However, arbitrum nova doesn't appear in the destination dropdown box, only arbitrum itself.

If this doesn't work, I'll wait until the Camelot partnership comes up in a couple of days, but I'm keen to swap my moons, and am just stuck at this step.

Any ideas?
