Unauthenticated paths for OAuth

[cod3dump]

I have integrated Grafana with authentik and it is working fine. However I was wondering if there's a way i can add unauthenticated paths like for forward proxy? I am not able to access /api on homepage and i'd like it such that /api doesnt go through authentik. I am using Caddy and only have the below entry for grafana in my caddyfile.

handle @grafana {
	reverse_proxy /* localhost:3000
}
