At least for now, you can use applescript
!osascript -e 'tell app "Terminal" to do script "./Astra charge"'
Except it looks like your starting directory is likely to be your home directory, so you probably need to specify a full path.
I see a claim that you can put two commands separated by semi-colon -- but I also see it claimed that two is the limit.
The reply from the above would look something like
tab 1 of window id 6550
which is information that can be used to control the application.
