While I extend the AbstractOIDCProtocolMapper to create My own CustomProtocolMapper, I create a List of ProviderConfigProperty. One of the ProviderConfigProperties is multivalued, and is working fine with hardcoded values/ Array of Strings.
However I need to add dynamic values into that property, either by reading an other protocol mapper or via an external API.
I tried to put that code in postInit method but it did not work. I guess the question is , Is there a Lifecycle method where I can call an External Or an Internal API once the keycloak server loads all its protocol mappers to dynamically add some values into the properties?
