What I´m trying to do is to condition some
option/modal to be shown in the screen depending on the logged
user/account being the owner or not so to have something similar to:
accountPair.address === NFT.owner
I know it has to be related with the addresses inside
keyring. But how do I identify the current account being logged in the UI? I´m working with the
front end template of polkadot js.
