Lost parameters in the mobile version when clicking on a link in a post?

Question

Mobile development

Good afternoon.
In the application group, I make a link https://ok.ru/game/mdragons?gift=a310
I need to pass this parameter to the application from both the large version of OK and the mobile one.
When I go to the large version of OK via the link, the application opens in an iframe, and in the parameters I see the following custom_args=gift=a310 (the parameter is passed, everything is ok!)
If I download the OK mobile application for android and click on the same link, then there is no parameter nowhere.
question:
how can I save these settings for the mobile version?
