I'm not familiar with this project, just checked their GitHub Readme and if I understand correctly they block what you want them to block. Sinkzone does the opposite, it allows what you want to allow, and blocks everything else.
Blocks everything except example.org and example.com.
Works in AdGuard Home, AdGuard DNS or any other AG product with DNS filtering capabilities: https://adguard-dns.io/kb/general/dns-filtering-syntax/
