Usage of credentials for Kafka Consumer

Hey everyone,

I am relatively new to node-red and I want to use it for demonstrating kafka streaming.

For this I have used the node-red-contrib-kafka-client node to build up a kafka producer and a kafka consumer. This all works fine, now I just want to include access control lists to regulate who can consume from the topic. How can I then use the credentials (username + pw) to login with my kafka consumer within node-red to receive the messages from the producer? I have not found a suitable node in the library so far.

Thanks,

Max
