I am trying out the connector with camunda 8.7. Could you please help here?

PS: Authentication used for the apps is default(demo/demo).

I am able to run the API (mentioned in the connectors log “path”:“/v2/process-definitions/search”) using default credentials but not sure how to tell to the Zeebe to use the same credentials when interacting with connectors & vice versa.

Hi,
Anyone tried this and can help here?
