Describe the current behavior in detail

Checked on https://wormhole-connect-mainnet.netlify.app/ [Mainnet] and https://wormhole-connect.netlify.app/ [Testnet] with macOS Sonoma 14.5 and Google Chrome Version 126.0.6478.127 (Official Build) (x86_64).

Steps:

1. Select Klaytn network as source chain
2. Connect MetaMask wallet in From section
3. Open Assets list

Actual Result: Only native assets are displayed (KLAY and wKLAY in this case).
