Does anyone know some kind of proxy for android that supports mTLS?

I host some personal services that are all reachable over the internet but secured by client certificates. For Android apps, this works if the app supports mTLS. Anyhow, is like to add some apps that don't support this, so my idea was to add a local proxy to my Android phone that connects to my server via client certificate and exposes a local port to my app to connect to.

Does anything like this exist?
