The server url and key you are using is hidden from other users on Github however they can download your client and connect to your server. If you require a fully private repo you can import the rustdesk client repo using https://github.com/new/import.
Once workflows are enabled you can click "Flutter Nightly Build" on the left then click "Run workflow" on the right to build the rustdesk clients for all of the supported platforms.
