YokaiSwap and using CKB

I am new to this but I don’t get it

so I got a nervos wallet with ckb in it
i have metamask but I cant seam to figure how to use it here with ckb
how do I use these 2 things to get my ckb into yokai
I’m definitely missing something

Yokai is kind of a pain. you have to go to the bridge tab and select deposit. Then you have to send CKB to L1 address on Yokai. After that you have to deposit into L2 and you can use the dex. Also keep in mind you have a 3 day wait to withdraw. IMO its to many steps and I don’t like the 3 day wait.
