macOS 11.4 , Alacritty 0.8.0 installed from homebrew 3.2.5 , although this should not matter because the question is mostly related to macOS UI.
What I want to do is something equivalent to Terminal.app's right click on icon > New Window sort of thing; Alacritty does not support windows.
On Linux, I'm used to launching new instance of alacritty with background option in dmenu.
On a mac, what would a similar action look like ?
I think pressing command + N does the trick
