Using Xcode Coding Agents with Custom Model Endpoints (Azure Foundry, etc.)

Trying to use the new built-in coding agents in Xcode (Claude / Codex), but running into a limitation with enterprise model setups.

Our org accesses models through Microsoft Foundry (Azure-hosted endpoints), and we can connect to those models in Xcode using a custom endpoint / URL. That part works.

However, that setup doesn’t seem to work with the built-in coding agents themselves. Those still appear to require direct account login or native API keys, with no way (that I can find) to point them at a custom endpoint or provider-backed deployment.

Anyone figured out a way to get the agent experience working with enterprise setups like Foundry (or proxy layers)? Or is that not supported yet?
