Can't set Ingestion API Key

[chfritz]

In our application we'd like to set the Ingestion API Key (as usually found on the teams settings page), rather than letting HyperDX auto-generate it. Following https://clickhouse.com/docs/use-cases/observability/clickstack/config#application-configuration-settings, I thought I could do that setting HYPERDX_API_KEY, but that doesn't seem to work (has no effect). I found #407, which seems to suggest I could overwrite the otel config -- which makes sense. But is there perhaps an easier way to do this via a different env var?

PS: I'm using the docker.hyperdx.io/hyperdx/hyperdx-all-in-one image

PPS: Also tried docker.hyperdx.io/hyperdx/hyperdx:2, same result.
