How to pass an application through a proxy?

Question

Mikrotik

Good afternoon. There is a Samsung TV with Smart TV. The Youtube app periodically comes across music videos that are blocked for viewing in the country.
Is it possible to somehow pass through the proxy only traffic from the application? Of the pieces of iron that are connected to the Internet, I have a router with OpenWRT and Mikrotik.
Thanks in advance for your replies.

Answer 1

If you change the condition a little to "let all smarttv traffic through a proxy" - the task will be solved many times easier

Answer 2

Well, I have Mikrotik, VPN is up.
further through the marking, some sites are wrapped in this VPN.
