Nginx settings for external redirection

Hello.

I have a running https instance of docker-jitsi-meet 5076 which I am accessing via

**https://<subdomain-name.<domain-name>.com**

and I have some other different docker containers running on the same machine. What I want is, when I enter

**https://<subdomain-name.<domain-name>.com/admin/files**

it should re-direct me to the containers exposed port. How do configure nginx for the web container ?
