HI @george_sb,
Welcome to the Auth0 Community!
As you’ve discussed, there are two main ways to implement a user invitation flow: customizing an email template and sending a change password email OR creating a password change ticket.
The password change ticket endpoint returns a URL that you are responsible for sending to the user.
The customizing the email template and ending the change password email requires you to customize the change password email template as described here and then sending that template to users via the Management API.
If you want the language to be changed, you will need to follow the customizing an email template and sending a change password email instructions as the password change ticket endpoint only returns a URL.

Please let me know if you have any additional questions!
Thanks,
Mary Beth
