localStorage.setItem('warning-close-account', true)Open up the token details of the token you want to remove. Send all the tokens of that single token type, for example, USDC, to a new wallet that you control (so that your token balances of the token you want to delete are zero). Then a Delete button will appear. Stop. Ask yourself if this is what you really want to do. If yes, then delete. It's strongly recommended to transfer all tokens to a new wallet after deleting an address. Again, if you ever send to a deleted address, you will incinerate your funds. Be careful.
