Depending on the wallet you're using, the networks supported by it and the general quality of said wallet, bridged tokens may not be detected and automatically show in your portfolio.
Here's a few steps to easily verify tokens have successfully been bridged.
Check the bridge in your Superbridge activity feed
If the bridge is successful there will be a transaction transferring the bridged asset to your address, double check it on the explorer to ensure everything looks OK.
Verify the tokens are present via a third party explorer
Tools like Etherscan, Blockscout, etc are great ways to check onchain that everything is as it should be, with an explorer you can easily see any ERC20 tokens associated with an address.
Make sure your wallet supports the network before you bridge
To see your tokens, or make transactions on a network your wallet must have support for it built-in, or allow to you add custom networks.
Wallets like MetaMask allow you to add custom networks. The network details such as chain ID and RPC URL should be available from the network's docs. If not please reach out to the networks team for support.
Manually enable the token in your wallet
Some wallets like MetaMask allow importing tokens in case they don't automatically show up.
