It opens a window without a shell

[Vinni-Cedraz]

Here is my config (lazy.nvim):

return {
"numtostr/FTerm.nvim",
config = function()
require("FTerm").setup({
cmd = os.getenv("SHELL"),
border = "double",
dimensions = {
height = 0.9,
width = 0.9,
},
})
end,
}

you can see I'm using the cmd = os.getenv("SHELL") but it has no effect:

There is nothing there, not even a shell.
