I have not seen a window AC with a schrader valve in probably 20 years. I have inspected maybe eight roof RV ACs, and none had a service port of any kind. I think the little sealed pigtail is where they they add refrigerant during the manufacturing.

That is also my understanding, few (if any) are made to receive "easy" recharges.
That may not be true for the basement mounted A/C found on some high-end DPs
