How to allow pop-up windows in the Yandex browser for android application?

Question

Android

I go from the tablet through the Yandex Browser application to the website of the Ministry of Health, in my personal account I need to go to training, but there I swear, they say, turn on the permission for pop-up windows for this site in the browser settings. I rummaged through all the settings in the application, I did not find anywhere about pop-up windows.
Tell me how it's done?
