Question

In contact with

If yes, then it turns out that in order to be able to send notifications to the user, you need to give him a link to this application, the user must then click "launch the application" and then return back to the site.
Are there any other options for activating the iframe application for the user, so that the process is similar to authorization through VKontakte, so that after the user allows the use of his data, the user is redirected back to the site.

Answer 1

In general, I shoveled all the possible options, read the documentation from cover to cover and came to the conclusion:

ps I will be glad if you refute my statements :)
