Get user task, claim and complete

Hi All,

I am using a self-managed Camunda 8 platform with zeebe-node (8.2.1) client in my application. But not able to find functions to get user task, claim and complete.

In Camunda 7 with REST engine, I am able to get task, claim and complete it through my application.

Can you please help me with same?

These are Tasklist / Operate functions, not part of the Zeebe core.
