[Koha] Koha :: users' expiration date

Hi, I need to change the users' expiration date. Evaluating the database, it is necessary to change the dateexpiry and updated_on fields. Is there another field or table? I intend to make the change directly in the database. thank you, Jose Ricardo Quaglio Public Library of São Bernardo do Campo – São Paulo - Brazil https://bibliotecapublica.saobernardo.sp.gov.br/
