            Use `docker` or `podman` to test this pull request locally.

            Run test server using develop.opencast.org as backend:
            ```
            podman run --rm -it -p 127.0.0.1:3000:3000 ${{ steps.meta.outputs.tags }}
            ```

            Specify a different backend like stable.opencast.org:
            ```
            podman run --rm -it -p 127.0.0.1:3000:3000 -e PROXY_TARGET=https://stable.opencast.org ${{ steps.meta.outputs.tags }}
            ```

            It may take a few seconds for the interface to spin up.
            It will then be available at http://127.0.0.1:3000.
            For more options you can pass on to the proxy, take a look at the `README.md`.
