Is it mandatory to declare the name of cookies inside the banner from a legal point of view?

No, it is not mandatory to list every cookie by name directly in the consent banner from a legal point of view. Under regulations like the GDPR, the requirement is to ensure transparency and informed consent. This means that while the consent banner must inform users that cookies are being used, along with their purpose, and provide the ability to accept or reject cookies, the specific names of the cookies do not have to be listed in the banner itself.
