Access keycloak secrets (clientIds, tokens, ldap etc) from hashicorp vault

I am using jboss/keycloak docker image (uses wildfly as app server) and we are leveraging keycloak as an identity broker and user federation. I want to store the keycloak specific secrets in hashicorp vault, and basically access these secrets at runtime.

The docs have mentions of kuberneter/openshift secrets and also Elytron credential store vault provider. There is no mention of hashicorp though. Currently I am looking at this extension. Wanted to know if we have better way of achieving this.
