@albertom-pirovano-mck thanks for the feature request.

As of now server does not keep registry of Workflow and Activity Types. But this is something that maybe we want to consider in the future.

Another approach would be to get the info via server APIs from the workers. But that requires 1) workers be running 2) user gives task queue name in the request so server knows which worker to get the info from.

Given the limitations of the second approach do you think it's going to still be helpful for your use case?
