Invite only user creation workflow

hi all, I have the basic/default workflow setup where the user gers a verification email etc.

What I need to do using Auth0 is:
1- admin Create User
2- user gets an ‘user invitation’ welcomeemail so they can set their new password with a link in the email

is the above possible without custom code? I don’t have a Web server/back end where I can host this code. I’ve read this Send Email Invitations for Application Signup.

but it looks like I need to have custom code that can generate an invite URL?
