I started hacking on a PR to add the metadata principal to the the agent proto - https://github.com/flyteorg/flyte/pull/5481 Like the recent console_url PR at https://github.com/flyteorg/flyte/pull/5449 from @high-accountant-32689, I think this is going to require an addition to the CR so that flytepropeller can pick up that value. I might have missed an alternative mechanism when scanning the code though, so if anyone knows that area better, please chime in. Thanks!

thank you. will take a look later today

The IDL definition should be pretty straightforward I also have some local code that I haven't pushed yet that's incomplete. I'll push that up for feedback / just so you can see where I was looking
