Instructions / example for using passiveMode = false + backfill?

[trauts2]

I've been able to follow the excellent instructions and get the example app working with my Dexcom G6. Example app works as expected in passive mode. But when passiveModeEnabledSwitch is on, I get "Unable to parse auth challenge: timeout".

I'd like to use this lib to extract data directly from the transmitter, without using the Dexcom app, and it clearly supports this feature.

But I don't see in either Loop code or this example app how to effectively request from the device ALL of the glucose data. Is this in use by any of the apps consuming CGMBLEKit that you're aware of?

My intention is to create a flutter wrapper of this functionality to use in a research app. Any guidance or suggestions?
