No term env when calling commands as :Term parameter ?

If I use use Term/VTerm/TTerm as usual, a get my shell prompt, the env is loaded.
As example I run my `ls` command alias (which is `alias ls='ls --color=auto` ), after entering a term and getting a prompt, all is Ok.

But if I run `:Term ls`, it doesn't seem to take into account the env, default ls is ran.
Is there a way to load the env wich direct command calls ?
