Reading stdout when interacting with a container via run_via_binary_in_foreground

[palmleon]

As the title says, it seems that there is no way to look at the output coming from a container when launching it in foreground. I would like to feed some input via stdin and then observe the output (or read it for checking sth), but I have no idea about how to do it, it seems it is not reported in the documentation. Any help would be greatly appreciated
