License for enterprise deployment in Kubernetes

Hi,

I just got the license for Neo4j Enterprise from startup program and have a basic question about deployment.

Right now, I'm deploying a Neo4j causal cluster into Kubernetes cluster with this helm chart:

In the values file, I only find this license related config:

acceptLicenseAgreement=yes

Q: Do I need to apply the license during the deployment or after?
If I don't apply the license, does it affect anything?

Regards,
Liwen
