remote debugging on linux is not working

i have a unity player running on another linux device(steamdeck), and i am trying to do some remote debugging on my ubuntu machine, but the device is not showing up on the process list and manually input the ip address of the steamdeck(which can be successfully ssh in) shows : " unable to connect to custom player. Please following "Debugging in Player" document.

I am wondering whether this is supported on linux?

Start with the Debugging in Player document and the remote connection path involving the process list and manually entered custom-player IP. Reproduce with a Unity player on a Steam Deck and an Ubuntu machine, then determine whether Linux remote debugging is supported and verify that the connection either works or reports the limitation clearly.
