Confidential Client in Dev Tier failing

Getting a failure for Foundry OAuth Private Credentials with a dev tier instance.

I recreated with this repo but re-read docs in depth and saw dev tier does not have access to client_credentials OAuth grant_type.

palantir.com/docs/foundry/ontology-sdk/how-to-bootstrapping-server-side-typescript

I then found it was a core feature of the Enterprise tier:

I think including this in Dev Tier would unlock lots of builders to really enable foundry as a backend and build more consumer apps (without your users needing a Foundry account to OAuth) but can totally understand this as a gate to get folks to upgrade account type.

Fwiw you can already do this with personal token and endpoints via direct calls, but without use of SDK.
