Keycloak 17 - How to add Quarkus Extensions?

I need to export logs to Graylog, and here Logging in Keycloak.X · Discussion #8870 · keycloak/keycloak · GitHub it’s recommended to use quarkus-logging-gelf extension, but I couldn’t find how to install quarkus extensions.

How do you add Quarkus Extensions to Keycloak 17?
Do I need to add the jar to providers folder similarly to Keycloak Extensions?
I am using the docker image provided at quay.io.

EDIT: Found a discussion at [KC17] [Logging] Running Keycloak as a container: how to send logs to logstash ? · Discussion #10884 · keycloak/keycloak · GitHub
