stETH via Coinbase Wallet – IS IT ERC-20?

Hello!
I am in a situation where I need to withdraw my stETH from a DAPP, but they only have my account linked via Coinbase Wallet.

I can't find any information online regarding Coinbase Wallet accepting stETH, and even their support team is refusing to outright answer that question (probably due to liability)

They are however confirming that Coinbase Wallet allows you to manage all ERC-20 tokens.

I just wanted a sanity check – can anyone confirm here whether stETH is ERC-20? Also has anyone here ever used the Coinbase Wallet as a bridge for their stETH at any point? As in, depositing in CB Wallet won't make me lose my stEth position….right?

Thank you
