[FEATURE] access point mode for wifi connections

[uglyoldbob]

I would like to be able to create a wifi connection with mode=ap instead of mode=infrastructure.

I see there is a https://docs.rs/nmrs/latest/nmrs/builders/fn.build_wifi_connection.html function and I can manually change the mode in the returned data, but I don't see a way to actually use that value anywhere. The docs mention AddAndActivateConnection in passing, with no indication of what it actually is or how to call it.
