How to implement forward multicast (bonjour) traffic between subnets via MikroTik?

Question

Mikrotik

Good afternoon. There are two subnets routed through MikroTik RB750, one has an AirPlay device from a well-known fruit company. What kind of magic needs to be done in the M-tic so that you can use this device from another? I read about crutches in the form of avahi + OpenWRT + METArouter, but this is not the path of a true Jedi. If you have experience, please share.
