Hey @Gazbo, happy to help! 
We are currently working on auto discovery to automatically add new assets sent to you wallet. https://github.com/brave/brave-browser/issues/26547
In the meantime you can manually add ERC20 tokens to your portfolio by clicking on the Visible Assets button on the portfolio page.
An easier way to add, is to go to https://www.coingecko.com/en/coins/verasity and click on the Add to Metamask button. Then click Add when the Brave Wallet prompt appears.
