Do I check whether a user has deleted their account or is banned during the verification or during refreshing of the token? This is related to adding checkDatabase boolean. I ask because: 1) in one GH issue https://github.com/supertokens/supertokens-core/issues/521#issuecomment-1280672975, it mentioned that I can override the refresh access token API 2) Documentation here https://supertokens.com/docs/emailpassword/common-customizations/sessions/access-token-blacklisting says, "This feature works by passing the checkDatabase option when verifying the session as shown below."
