Form Withdrawal

-- HikaShop version -- : 6.5.0
-- Joomla version -- : 5.4.6
-- PHP version -- : 8.4
-- Browser(s) name and version -- : all
-- Error-message(debug-mod must be tuned on) -- : Problem with Form "Withdrawal"

My question: the menu item `...index.php?option=com_hikashop&view=withdrawal&layout=form` leads to a form where I am required to log in using a username and password; however, I do not have either of these credentials. Where can I edit this form?
Thanks in advance
Anja
