Kafka connector connection

i am trying to create kafka connector connection in Ignition 8.3.4, i am using trial version of ignition and kafka module. I tried to use the local kafka broker whihc i use for testing, tried remote broker. The create connection button never enabled, no errors shown.

has anyone tried this with local kafka setup, no need for username and password ? are TLS setting must have like no way connector can connect to non tls broker ? is it license issue ?
