Temporal Nexus for external http

Hi Temporal team,

A Nexus Endpoint name is used in Workflow code to invoke Nexus Operations. The endpoint target may either be a Worker, in which case --target-namespace and --target-task-queue must both be provided, or an external URL, in which case --target-url must be provided.

May i know how should we implement nexus codes to connect to target-url?

Best regards,
Jx
