help request: integrate apisix with wso2 management

### Description

Hi Team,
I’m looking to integrate Apache APISIX Gateway with WSO2 API Manager. APISIX is running in one Kubernetes cluster, and WSO2 APIM is deployed in another cluster. Both clusters are connected via the same Transit Gateway network. What’s the recommended approach for integrating them for API management and runtime traffic? Please provide the recommended approach and any related docs will use for me. Or is there any agent to run separately to integrate with wso2. please help on this, planning for production. Thank you.

### Environment

- APISIX version (run `apisix version`):
- Operating system (run `uname -a`):
- OpenResty / Nginx version (run `openresty -V` or `nginx -V`):
- etcd version, if relevant (run `curl http://127.0.0.1:9090/v1/server_info`):
- APISIX Dashboard version, if relevant:
- Plugin runner version, for issues related to plugin runners:
- LuaRocks version, for installation issues (run `luarocks --version`):

Start by reviewing the described APISIX and WSO2 deployments, including the separate Kubernetes clusters and shared Transit Gateway network. A useful outcome would be documented, production-oriented integration guidance covering API management, runtime traffic, and whether a separate agent is required; the issue does not identify an implementation file or test.
