Help with changing sonarr user

Sonarr version v3:
Mono version latest:
ubuntu 20.04:
I followed the official guide to install sonarr from here https://sonarr.tv/#downloads-v3-linux-ubuntu, I let it setup the user and group as default sonarr user and group. However with those settings I was unable to access my external drives so I need to change the user and group, I’ve tried removing sonarr, deleting the user and group and installing it, but it always sets up as sonarr user and group only. Can anyone help me? Thanks.

Just in case someone finds this post.
As mentioned on discord: dpkg-reconfigure sonarr for sonarr v3.
