Hi @TIKaushik
Thank you for contributing to the Opencast Admin UI.
We noticed that you have not yet filed an Individual Contributor License Agreement. Doing that (once) helps us to ensure that Opencast stays free for all. If you make your contribution on behalf of an institution, you might also want to file a Corporate Contributor License Agreement (giving you as individual contributor a bit more security as well). It can take a while for this bot to find out about new filings, so if you just filed one or both of the above do not worry about this message!
Please let us know if you have any questions regarding the CLA.

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 ghcr.io/opencast/opencast-admin-interface:pr-1315

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 ghcr.io/opencast/opencast-admin-interface:pr-1315

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.
