How to relay scrobbling to ListenBrainz

[jostyee]

Hi music lovers,

In maloja README there's a block says:

Proxy Scrobble: No need to fully commit or set up every client twice - you can configure your Maloja server to forward your scrobbles to other services.

I'd like to use maloja to scrobble to my ListenBrainz as well (for backup), but adding below envs to the docker-compose.yml don't work as I expected:

- MALOJA_OTHER_MALOJA_URL=https://api.listenbrainz.org
- MALOJA_OTHER_MALOJA_API_KEY=$MY_LISTENBRAINZ_TOKEN

Is there anything I missed? Thanks in advance.
