You want to just tail it with tail right? https://docs.fluentbit.io/manual/pipeline/inputs/tail

Just set it up to read it from wherever you mount it into the Fluent Bit container.
The official helm chart supports custom mounts: https://github.com/fluent/helm-charts/blob/410629ed113fe5c0f5a27dfff4c6a5e08640d0ca/charts/fluent-bit/values.yaml#L347-L349
