Add the gpg key used to sign the packages by running the following wget | gpg | tee >/dev/null command

I was preparing my Kali Linux to run a Tor's Middle Relay. I was doing Tor Project's Repository configuration according to this site . I made steps 1 and 2. The 3rd step was to add the gpg key used to sign the packages by running the following command:

sudo wget -qO- https://deb.torproject.org/torproject.org/A3C4F0F979CAA22CDBA8F512EE8CBC9E886DDD89.asc  | gpg --dearmor | tee /usr/share/keyrings/tor-archive-keyring.gpg >/dev/null

The problem is I don't understand what this command does and why it fails, even though I execute it with

permissions.

└─$ sudo wget -qO- https://deb.torproject.org/torproject.org/A3C4F0F979CAA22CDBA8F512EE8CBC9E886DDD89.asc  | gpg --dearmor | tee /usr/share/keyrings/tor-archive-keyring.gpg >/dev/null
[sudo] password for michal: tee: /usr/share/keyrings/tor-archive-keyring.gpg: Permission denied

This part with

, I understand. But I don't know what is happening after the tor repo gets downloaded to my vps.
