Sample authenticator SPI not populated in UI

Hi Keycloak community,

I am new to Keycloak and plan to develop a custom authenticator SPI to enable the MFA. Before that I have tried on the out-of-the-box “secret question” example. I have used maven to compiled the jar file to copied it to the /deployments folder (v10.0.2) in my docker container. However, when I navigate to the admin UI and tried to select from the executor dropdown in the copied “browser” flow, I cannot find the “secret question” being populated, and there is no error from the keycloak logs.

Is there any way I could further troubleshoot this issue? I have tried an sample event-listener SPI before using the similar steps and everything works perfectly.
