Encrypted dns, rethink dns

I’m using rethinkdns android v0.5.5n My goal is using brave android with encrypted dns but without setting up secure dns inside the app and using cromite android on wireguard rethinkdns. I already try the methods on your reply but not working and not a line to my goal. I don’t know if rethink dns android have that feature. Already try lates beta version but not working to me. Sorry english is not my language.
