Docker containers can't write inside cifs share

Question

I have a docker compose for a media server i'm building using multiple containers, i want these containers to be able to R/W a cifs share mounted on host, after trying multiple ways i can't seem get them to write. here's the mounted share : /etc/fstab

//192.168.X.X/Media /mnt/Media cifs cache=loose,credentials=/root/.smbcrd,vers=3.0 0 0

and here's one of the multiple containers docker compose :

 emby:
image: linuxserver/emby
container_name: emby
environment:
  - PUID=998
  - PGID=100
  - TZ=Europe/Paris
  - UMASK_SET=022 #optional
volumes:
  - /mnt/Media/Configs/Emby:/config
  - /mnt/Media/Series:/data/series
  - /mnt/Media/Films:/data/movies
ports:
  - 8096:8096
  - 8920:8920 
restart: unless-stopped

I'm learning docker and i don't think mounting the cifs share inside every container is the solution,do i need to mount the share in volumes section of my docker compose ?,the share is a synology nas. can anyone help?
