I made a simple site with python-flask and hosted it on heroku. I also have a wordpress website where I often post article about python. Now I want to embed the whole heroku site to a alias of my wordpress Website. Suppose, My wordpress is on my-wp-web.xyz and my heroku website is on simple-flask-app.herokuapp.com. Now I want to access simple-flask-app.herokuapp.com from my-wp-web.xyz/flask-app without redirecting. Is there any DNS settings, wp plugins or anything?
Note: The wp site was hosted from Direct Admin not from CPanel.
