Mutual TLS implementation for Akka Http Client and Akka Http Server or Other Server

Akka Akka Streams & Alpakka

Need to use Mutual TLS to transfer data via https . Both in Client and Server

Client will be Akka Http ,
For Now server is also build in Akka http by us.
But there is a chance we need to connect to a another flavour like Amazon API Gateway or Azure API gateway or Legacy J2EE or .Net Servers or Web Services

Went through the document , but not getting it , no samples also on TLS side.
Anybody tried ,in steps or some samples will be helpful .

But you have read Using HTTPS (server) and SSL config (client)?
