How to connect Keycloak (helm) with Oracle Cloud Autonomous Database ATP

app.kubernetes.io/version :11.0.2
helm.sh/chart : keycloak-9.5.0`
repo source: https://github.com/codecentric/helm-charts.git

Question:
How and where is the jar file stored? which directory? Does keycloak support this?
source of the ATP information: google database/technologies/java-connectivity-to-atp

Where and what env var to use for the jdbc url? What are the configurations to change?

How can this be integrated in helm chart? How to configure the wallet and which directory are they stored in?

Thank you
