Closing a savings pot - how do I do it?

I’ve seen that the current savings pots are offering double the rate of interest on my paragon ones. How do I close them so I can move them over? It prompts that I have to leave £10 in a pot. I can’t see an option to completely close. Or do I archive the pot, let my money move to my account then open new savings pots? It’s not that clear in the help guides.

Exactly that.

There should be a little archive icon in the top right corner. Looks like a storage box. Clicking that closes it.
