I am installing prometheus-stack using helm charts in my k8s cluster and the deployment uses argocd. In my values.yaml file I have defined different jobs. Couple of jobs needed authentication and I gave it like  
basic\_auth:  
username:   
password:

I want to pick these credentials from the secret in the cluster. But looks like prometheus helm does not supports it. Also I tried to get the value from env variable by mounting the secret in the pod. but looks like that is also not supported. Can you please suggest a solution for this. How can I avoid hardcoding the credentials in values.yaml file?
