How to create https proxy tunnel on localhost port so apps without https proxy support can work with it?

Question

What I need: take https proxy, put in on some localhost port, so if local app connects to this port, all traffic it gets will go through https proxy. Linux.

Details: app ( headless Selenium chromedriver ) can't work with HTTPS proxies (only HTTP). Also, I can't initiate app through something like proxychains (app starts from inside the Python script as a function). So, I want to create localhost port for each external https proxy and connect to ports from inside the app like to simple HTTP proxy.

Is it possible and how?
