What does BLEServer connect() do, exactly?

In the course of trying to figure out why terminating BLEClient connections also disconnects BLEServer connections, I found that BLEServer has a connect() method just like BLEClient. I managed to call it on a BLEAdvertisedDevice, but nothing really happened. What is it supposed to do? It seems like it forcibly connects the client to the server? But why would that be desirable?

If the peer (the client in the case of BLEServer) is advertising a service, connect to it. The note in the code (
https://github.com/espressif/arduino-es ... #L334-L335) says "Allow to connect GATT server to peer device. Probably can be used in ANCS for iPhone"

Forgive my inexperience, but I thought services only existed on the server side? Does this mean that the client device has to be dual-mode BLE (like the ESP32 is)? There's no way in BLEClient.h to create a service AFAIK.
