Quit from custom commands

[noahfraiture]

Hello,
I don't see anything in the custom commands to quit lazygit. I want to integrate lazygit in helix like it can be done in yazi sxyazi/yazi#2461 and thus I have the following lazygit command

          key = "o";
          context = "files";
          command = "echo {{ .SelectedFile.Name }} > /tmp/lazygit-path; exit";
          description = "Write the path in tmp file to be open with helix";

And this helix command

            "l" = [
              ":sh rm -f /tmp/lazygit-path"
              ":write-all"
              ":new"
              ":insert-output lazygit"
              '':insert-output echo "\x1b[?1049h\x1b[?2004h" > /dev/tty''
              ":buffer-close!"
              ":open %sh{cat /tmp/lazygit-path}"
              ":redraw"
              ":reload-all"
              ":set mouse false"
              ":set mouse true"
            ];

However the exit in the command doesn't work obviously because under the hood it's a command bash bash -c and it's that process that exit. A solution is to use a signal with something like ...; kill $PPID but it's probably not the best way as generate an error.
Is there another solution or is there a good signal to use ?

This is a little bit of topic but I ask here if someone know, after doing this helix trick, the terminal is buggy and pressing the escape command in lazygit doesn't exist a menu, but print [27u. Do you know where that comes from ?
