Command line – Lubuntu 18.10 QTerminal Transparent Setting?

The default terminal in Lubuntu 18.10 is QTerminal. In one way or another, I have not found any transparency settings anywhere.

I found an almost similar question here. The transparency of the Lubuntu terminal

Unfortunately, this concerns LXterminal in Ubuntu 18.04.1 LTS.

Would it be possible to do this in the Lubuntu QTerminal 18.10? If so, please let me know how.

If not, what is the alternative?
