There is a reason the hose is only 5 feet long.

The air conditioner's exhaust fan is only sized to push the air
through 5 feet of hose. A longer hose will kill the air conditioner's
efficiency by restricting the airflow and giving the warm air 2-1/2
times as much surface area to pass its heat back into the room. It's a
double-whammy.

Those kinds of air conditioners are meant to be placed near a window.
