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:

version: "3.7"

services:
  prowlarr:
    container_name: prowlarr
    image: ghcr.io/hotio/prowlarr
    ports:
      - "9696:9696"
    environment:
      - PUID=1000
      - PGID=1000
      - UMASK=002
      - TZ=ETC/GMT
    volumes:
      - '/home/${USER}/server/configs/prowlarr:/config'
    restart: unless-stopped
  sonarr:
    image: lscr.io/linuxserver/sonarr:latest
    container_name: sonarr
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=ETC/GMT
    volumes:
      - '/home/${USER}/server/configs/sonarr:/config'
      - '/home/${USER}/server:/data'
    ports:
      - 8989:8989
    restart: unless-stopped
  radarr:
    image: lscr.io/linuxserver/radarr:latest
    container_name: radarr
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=ETC/GMT
    volumes:
      - '/home/${USER}/server/configs:/config'
      - '/home/${USER}/server:/data'
    ports:
      - 7878:7878
    restart: unless-stopped
  jellyfin:
    image: lscr.io/linuxserver/jellyfin:latest
    container_name: jellyfin
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=ETC/GMT
    volumes:
      - '/home/${USER}/server/configs/jellyfin:/config'
      - '/home/${USER}/server/media:/data/media'
    ports:
      - 8096:8096
    restart: unless-stopped
  qbittorrent:
    image: lscr.io/linuxserver/qbittorrent:latest
    container_name: qbittorrent
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Etc/UTC
      - WEBUI_PORT=8080
    volumes:
      - '/home/${USER}/server/configs/qflood:/config'
      - '/home/${USER}/server/torrents:/data/torrents'
    ports:
      - 8080:8080
      - 6881:6881
      - 6881:6881/udp
    restart: unless-stopped
