Need Guidance on Routing Docker Container Traffic through a Wireguard VPN

Hey there, I’m a newbie when it comes to self-hosting and working with Docker. I’m looking to route traffic from a couple of my Docker containers (specifically, qBittorrent and Prowlarr) through a Wireguard container that’s hooked up to Mullvad. Any tips on how to set this up?

Here is my compose file:
