Ledger s connected to yoroi

Trying to stake my ada in yoroi testnet wallet.
Is there a step by step guide on this?
have already installed the yoroi testnet wallet on my chrome browser.
How do i import my wallet when it does not give me the ledger nano s option.
must be missing something.

unfortunately you wont be able to delegate using a LEDGER wallet in the ITN.

only Deadalus , Yoroi, and paper wallets from what I remember.
