Double Opt-in for account Registration


I am new to Shopware. Lately I have been working on email templates in Shopware 6. I am working on double opt-in registration Email template and I cannot find the variable for the link I need to put in the Double opt-in Registration email (not for the newsletter but for the account registartion) for confirmation of account registration. In the newsletter double opt-in template there is a variable that I can use to provide the confirmation link but I could not find any in the the template of double opt-in registration.

It would be a great help if someone could guide me a bit on this topic or let me know where I can find the variable/link that I need to put in the Double opt-in registration. Thanks in advance.
