Cifs share on stack docker

[manustar]

hi all, I state that I am not an expert on proxmox and I am seeing many guides, I have followed the various posts to mount a cifs and give permissions to an lcx and from the console I can create folders (before I had access denied), having said that i created a stack on portainer for docker creation but let's all say it gives me access denied on volumes. this is my stack and i can't figure out where i go wrong

services:
    frigate:
      container_name: frigate
      image: ghcr.io/blakeblackshear/frigate:stable
      restart: unless-stopped
      devices:
        - /dev/dri/renderD128
      volumes:
        - /etc/localtime:/etc/localtime
        - /root/frigate:/config:rw
        - /media/NAS/frigate/clips:/media/frigate/clips:rw
        - /media/NAS/frigate/records:/media/frigate/recordings:rw
      ports:
        - 5000:5000
        - 1935:1935

    prometheus:
      image: prom/prometheus:latest
      container_name: prometheus
      ports:
        - "9090:9090"
      volumes:
        - /media/NAS/datadocker/prometheus/etc:/etc/prometheus
        - /media/NAS/datadocker/prometheus:/prometheus
      restart: unless-stopped
      command:
         - "--config.file=/media/NAS/datadocker/prometheus/etc
#        - "--config.file=/etc/prometheus/prometheus.yml"

    grafana:
      image: grafana/grafana:latest
      container_name: grafana
      ports:
        - "3000:3000"
      volumes:
        - /media/NAS/datadocker/grafana:/var/lib/grafana
#        - grafana-data:/var/lib/grafana
      restart: unless-stopped
#volumes:
#    prometheus_data: {}
#    grafana_data: {}

and this fstab
