There is a case that possibly happens that you don't want Snowflake to no longer use your SPL token on your behalf. Don't worry, the good news is there's a way for you to revoke the allowances that you made. In the Settings tab, scroll down to the "You Wallet" section, next to the Authorize button, there is a button called Revoke. Clicking on that button will pop up a modal for revoking token allowances. Just select a token that you want to revoke and the process is completely done.
