Once your Gallery has been updated on chain, you can click on an FNFT inside of it. After clicking on an FNFT, it will open up and show you more information, such as the date the FNFT was minted, and the date at which it will unlock.
You also have option to send your FNFT to another address, and once the time lock has completed you can withdraw your assets by clicking "Withdraw" at the bottom of the page.
