Trying to connect to a second machine via Advanced->SCP->Shell

Hi,
Recently, I have reinstalled Ubuntu on a remote machine. To connect to the machine from home, I have to ssh to a gateway and from there I have to ssh to the local machine I want. Therefore, in the gateway, I have write a file ssh_to_rtx3080 with the content of ssh rtx3080. I give the path to the file in WinSCP->Advanced->SCP->Shell. But as you can see in the picture, I get an error that server connection is closed.

When I use the terminal on the gateway, there is no problem with that file.
$ cat ssh_to_rtx3080

ssh rtx3080
$ ./ssh_to_rtx3080

I have read the FAQ https://winscp.net/eng/docs/message_unexpected_close but I don't understand what is the problem exactly. Any idea about that?
