Do jitsi-meet-turnserver is required

I have installed jitsi-meet using this doc (Self-Hosting Guide - Debian/Ubuntu server · Jitsi Meet Handbook). It installed successfully.

While installing PHP in the same machine, i got information from terminal that jitsi-meet-turnserver removed and checked installed packages in that machine, I see coturn installed and other jitsi components, not found jitsi-meet-turnserver.

Is jitsi-meet-turnserver is required to run jitsi meet?

That is used in some cases where p2p is not possible to connect the 2 participants. Or if you are in a restricted network and cannot send UDP to the video bridge, you send TCP through the turnserver to the bridge.
