Can I expose docker web directory to host?

[bullXcd]

Hi, I have installed plausible on server with webiinoly nginx site manager.
Plausible is installed on port 8000 so I configured it as reverse proxy site in Webinoly.
Now I need to install SSL (letsencrypt) for this site. To do this with Webinoly, I need to provide path for web directory
sudo site example.com -ssl=on -root-path=/opt/myapp/web
But in default docker-compose.yml there is no exposed volume with app.
Is it possible to add some volume config to expose app directory on host?
