How do I tell MacOS to open TextEdit app at certain X and Y coordinates using a plist variable?

I've been looking at plist variables while trying to set the position and size of a window when the editor is launched. But I'm failing to guess or find the name of plist key for this. I was following similar advice here but without success so far. defaults read $HOME/Library/Containers/com.apple.TextEdit/Data/Library/Preferences/com.apple.TextEdit.plist HeightInChars I'm not working with multiple monitors which I hope makes it easier.
