This function allows obscure the email provided by the user so that, in a scenario where the email is requested, it is not directly disclosed on the screen, thus reducing the risk of data theft by malicious entities. Instead, it provides the user with only some hints. To use this function, it is available in the "ObscuredEmail_CS" service. By including the "ObscureEmail" action in a client action in the frontend module, you simply need to provide an email as input, and the function will transform the email, returning a disguised email as output. You can also edit the default values of local variables to camouflage more or fewer characters.
