How to change language in iframe?

Question

Angular

Good afternoon, please help me solve the problem.
There are 2 applications (rails), one is hooked up to another by means of iframe.
It is necessary to implement using angular-translate so that when the language changes in the main application, the language also changes in the frame.
ps if you switch in the frame, then everything switches.
