How to redirect after user chooses password with Accounts.sendEnrollmentEmail?

In my application many users are created on the server and a link to sign-up is sent using Accounts.sendEnrollmentEmail. That works great.

After the new user has clicked the link and chosen a password, I would like to send them to a specific route, but I have no idea how to do that.

I am using Iron Router and Accounts Entry (though Accounts Entry doesn’t appear to be have anything with this part of the account process).

I’ve googled the heck out of this, but it doesn’t seem like others have had this issue.

I googled Iron Router Accounts.onEnrollmentLink

And found this answer
