Redirect user to the previous route after a successful login - Flow-Router

Question

Using Meteor and FlowRouter for my website, I'm trying to get the following result.

A user receive a mail containing a link to a specific page of our website.

• if the user is already logged on the website, he access the page successfully
• if he's not, he's redirected to the login page. But I would like my user to be redirected to the page he was supposed to access at first after the successful login.

I put my route in PrivateRoute.js. This way I can redirect my user to the login page if he's not logged in. But I don't know how to redirect my user after that. Is there a way to achieve that using FlowRouter and Meteor? Thanks in advance.

Edit 1: Here is the code I use in PrivateRoute.js:

privateRoutes.route('/test', {
  action() {
    BlazeLayout.render('MainLayout', {
      main: 'test'
    });
    $(document).ready(function() {
      $(this).scrollTop(0);
    });
  },
  name: 'test',
});
