Wanted to test Eth Sepolia Testnet before going live

I’m trying to test out this plugin to see how it works out. When testnet is selected it will allow to connect a wallet but then it’s searching for the coin and just spins. If I connect to Eth mainnet ERC20 I can connect to the wallet and proceed to checkout. I’ve registered at https://www.alchemy.com/faucets/ethereum-sepolia and successfully send test coin to my wallet. I’m using a coinbase wallet for context.

Is there something I am doing wrong to be able to test this out?
