I am trying to launch a new gnome-terminal with a command executed

When I execute `gnome-terminal`, a new terminal opens smoothly.

Now when I run this

`gnome-terminal -- "zsh; echo hello"`

I expect a new terminal with zsh to open, with hello printed.

But what I get is a new terminal with this:

```
There was an error creating the child process for this terminal
Failed to execute child process “zsh; echo hello” (No such file or directory)

```

Some important results

Please take a look

```sh

❯ gnome-terminal -e "echo hello"
# Option “-e” is deprecated and might be removed in a later version of gnome-terminal.
# Use “-- ” to terminate the options and put the command line to execute after it.
❯ gnome-terminal --command "echo hello"
# Option “--command” is deprecated and might be removed in a later version of gnome-terminal.
# Use “-- ” to terminate the options and put the command line to execute after it.

```

Executing the following lines, does something like some ghost moves on the screen, but produces no visible output

```sh
❯ gnome-terminal --window -- echo hello
❯ gnome-terminal --tab -- echo hello
❯ gnome-terminal --tab -- echo hello
❯ gnome-terminal --tab --wait  -- echo hello

```

Where am I making mistake ? How can do do my intended job ie launch a new zsh terminal with hello printed, and waiting for next command
