i need to check in my dapp when the metadata of my wallet is expired and show a popup telling the user that he needs to update his metadata by clicking an update button on that popup.
i need to do this so that the user can always see all the transaction data when making a transaction, if the metadata is not updated he will see some hex code.
How can i update the metadata from inside my app using polkadot.js library ? Can i do this using some other library ? Is there any other library that is better than polkadot.js ?
