Where is the WebRoot for AdGuard?

[vlsalsa]

I have installed AdGuard properly on my home network on a Raspberry Pi 3.

I am working on trying to install an SSL certificate to access it over a domain and a cloudflare tunnel. As I go to install a certificate with Certbot, I am being asked on the Raspberry pi for the webroot location...

where does the webroot install on a standard installation of AdGuard on the Raspberry Pi?

use standalone instead webroot

sudo certbot certonly --standalone
