How Do I Create Ground Survey Teams?

All I could find is some 9 year old post on Reddit referencing some mythical "population window" which seem to no longer exist in the current version. I tied looking under Ground Units - nope, that's just combat units. Tried under Colony Tab - nope, no actions to be taken there, I've gone through pretty much the entire set of windows and tabs and can't seem to find any option to create anyone capable of doing a ground survey anywhere. I also can't find any current tutorials on how to do this either, just that aforementioned 9 year old reddit reply that's no longer relevant.
