Cannot authenticate trivy operator to private docker registry

[madhavansri2022]

I followed the docs(https://aquasecurity.github.io/trivy-operator/v0.5.0/tutorials/private-registries/) for authenticating our private registry to scan images. Only the first option seems to work.But we are not comfortable running Trivy as root. The second,third and fourth options seem to get ACCESS DENIED error. I could see that error in the logs.
Logs:
"Error","status.message":"time\t\u001b[31mFATAL\u001b[0m\timage scan error: scan error: unable to initialize a scanner: unable to initialize a docker scanner: 4 errors occurred:\n\t* unable to inspect the image (registry.private.com/project:4**7): Cannot connect to the Docker daemon at unix:///var/run/docker.sock.

Note: I did try above options with the recommended token format.

And also we have a gitlab registry for our images. And we've been following this format for registry authentication.
{"ghcr.io":{"username":"","password":"","email":"","auth":""}}.
Also do we require docker in Trivy operator container to pull images from registries?

I created the docker config with kubectl like described here

https://kubernetes.io/docs/tasks/configure-pod-container/pull-image-private-registry/

kubectl create secret docker-registry regcred --docker-server=<your-registry-server> --docker-username=<your-name> --docker-password=<your-pword> --docker-email=<your-email>

creted In the trivy namespace and defined the secret in the PullSecret block in the Values.yaml

trivy-operator/deploy/helm/values.yaml

Line 126 in 1b69d4a

pullSecrets: []

It works for me with Azure ACR
