Full screen apps remembering monitor on replug in?

[Storm312]

At work I like to full screen slack and spotify on my laptop. I have two external displays I use for dev. When I unplug my external displays and then replug them in, my slack and spotify full screen apps end up always on a certain external display and I have to move them back to laptop. Such a minor sounding thing but it happens at least once everyday and just slowly gets annoying. Is there any way to get it back to the way it was either through a setting or even an API? From what I've researched the macOS API doesn't have much to offer on managing spaces/full screen apps but hoping there's something... hammerspoon maybe?

have you tried toggling "Displays have separate Spaces" in System Prefs > Mission Control?

I have it on currently and honestly can't remember what the behaviors are when it's off. I can try it but I remember turning it on for some reason a while back.

I run with it Off in my multi-screen dock setup, but I do not use Full Screen ever so I can't say if it'll help.
