Hi

What is your scenario? Why do you want to route from activity?

Ideally the routing can be handled on Assignment shape in the flow.

Bhavya

As mentioned earlier by Bhavya, we can define the Workqueue/Workbasket from the Assignment shape itself.

If you really wanted to do from Activity, Call the OOTB Work-.ToWorkbasket from your activity.

some other helpful approach:
