Hi, I am building a custom registration flow in our keycloak app. What I already did is written a new provider that implements FormActoin and FormActionFactory. I also did add a new flow in the admin panel. The problem that I have is that I don't know how to link my flow to my new provider (it dont show up in the drop down when I do /Add execution/).  Do I need to add something to standalone.xml or do I miss something bigger? The documentation is not very useful , from http://www.keycloak.org/docs/3.3/server_development/topics/auth-spi.html :/" I’m hoping the UI is intuitive enough so that you can figure out for yourself how to create a flow and add the FormAction."/ Thanks Daan
