trying to add USDC on base sepolia to the rainbow browser extension (brave) is this supported? - USDC doesn't show up in my token list even though I have a balance - pasting the USDC address shows a loading state, then red outlines on the other 3 inputs until I fill them out - clicking 'Add' usually does nothing I don't wanna use fox app for dev but it's cumbersome to transfer USDC via basescan
