Kong Gateway Plugin for email register / sign-up

I am looking for a Kong Gateway plugin that I can allow the end user to register / sign-up by themselves with their mailboxes.

so after registered, a mail should be sent to their mailbox with the link to active their account, then they can login via email box with password, or if possible to set an unique username with password.

Are there any exist plugins for this requirement?

Note:

currently i run Kong Gateway Enterprise with Free mode
