Restart Libre 2 sensor

Can we do this and how? I was testing one and it stopped tonight finally. I figured I may as well try because it was handy to look at it when dex was on the blink a lot with a sensor that just failed earlier today.

Not happening

Apparently you can extend it for a day or two with outside apps etc. according to this video. I don’t have any of them like x drip etc. I don’t even know how to use them- are there any instructions for that here anywhere? I also have an iPhone and it seems from the video they maybe only work on android phones?
