Multiple monitors: open new window on the screen with mouse

With macOS Sequoia with multiple monitors, how can I make apps open new windows on the screen where the mouse currently is? I drag certain windows onto the secondary monitor (grep-ing a log in terminal, playing a video in youtube etc) and when I close the last window of the app on the main monitor, select the app from dock on the main monitor and click "cmd-n" for a new window, it gets opened next to the remaining active window of the app on the secondary monitor. This makes no sense to me.
