How can I make sure binance is using Segwit to transfer my BTC?

Hey guys,

The recipient wallet is Segwit BTC address (starts with "bc1")

On binance support page it says that Binance supports Segwit.

However what confuses me is that when you look at binance withdrawal fee schedule it shows the below fees

• BTC = 0.00057 withdrawal fee
• BTC(Segwit) 0.0005

When I enter my BTC address and choose BTC network (there's only 1 network and it doesn't say whether it's legacy or Segwit) The transaction fee is 0.00057 which according to their schedule fee is the fee charged for the legacy network.

I wouldn't want to send my BTC using the wrong network as I'd loose my BTC.

Anyone know how I should do to make sure I'm using thd Segwit network?
