Add rôle and launche instance

In Camunda 8 Cloud, how to add roles, in previous versions it was possible to add groups to assign tasks?
Other than in the modeler, how can I launch a stream instance?
Thank you.

Hey @nchoulant and welcome to the Camunda Forum! :slight_smile:
When having created a user task in Camunda 8 you can set assignees and candidate groups as well.
A good resource to look at can be found here.

I guess by referring to a “stream instance” you actually mean a process instance?
These can also be started by using a gRPC call.

Let me know if you have further questions!
