You cant. Leodex is a DEX, meaning crypto to crypto. From there, you can move your coins to a CEX like Coinbase.
Personally I swap on LeoDex to USDC, then move that to Coinbase since they charge zero fees on stablecoins (either receiving or converting to USD).
Once the USDC is in CB, I convert to USD and sent to my bank account.
