Container's volume is path or name, only one can be found docker volumes

General

I copy pasted from a github page to create a container of firefox with the first command

docker run -d --name=try_firefox --restart always -p 5822:5800 -v /docker/appdata/try_firefox:/config:rw jlesage/firefox

docker run -d --name=try_firefox --restart always -p 5822:5800 -v try_firefox:/config:rw jlesage/firefox

the volume is not findable with docker volumes unless I use the second construction. where does the volume live in the first construction?

the bargain VPS is running ubuntu2204lts

The first one is not a volume but a bind mounted local folder and it is the path on the Docker host.
