Cannot find app "green-recorder" in "green-recorder"

I installed green-recorder on Ubuntu 22.04 but it does not start: corrado@corrado-n3-jj-0103:~$ snap info green-recorder

this snap has only been pushed to the edge channel and never saw a stable release … edge snaps are often still in development (or in this particular one probably a failed/abandoned attempt to package it since it has not been touched since nearly 4y)

the snap command usually warns you about potential instability when installing from --edge … did it not do this ?
