Custom identity service for standalone service

I’m trying to implement a custom identity provider for my camunda standalone service, I have the 7.15.2-ee for Apache Tomcat version.

I already managed to create this custom identity provider implementing ReadOnlyIdentityProvider and tested it against the embedded camunda inside an spring boot application, but I can’t make it work in the standalone server, I don’t understand which files should I modify to accomplish this and I don’t see any examples
