Question about Magnific Popup. Multi-window?

Question

JavaScript

How to open the previous popup when closing the current one, if the current one was opened from the previous one?
How to improve it?

There is a popup with a form and there is a popup with a privacy policy.
The link to the policy is on the page and in the popup with the form.
If the policy is opened from a form, the form must remain when the policy is closed.

The example is working, but not universal, I feel it can be done more elegantly.
Who faced?

Answer 1

Make a separate page separate for the privacy policy.
