Kong with HTTPS (TLS 1.2)

Hi, I have few routes and services configured with Kong (DB mode) and by default they are all exposed with HTTP endpoints.

We have a requirement where I would like to secure all the Routes/APIs (not Kong Admin APIs) with HTTPS TLS 1.2.

I cannot find any plugins to perform this.
What is the correct way to implement this?
Is there any step by step guide available?
