Wyze Earbuds Pro on-line manual

Where is the Wyze Earbuds Pro on-line manual? There are no instructions on-line on how to pair these earbuds and how to switch from one previously paired device to the next. There is some vague reference to that here: Wyze Buds Pro Needs Dual Bluetooth Device Connection Desperately! - #7 by adamsmugala.

Yes, I know there is a pairing button on the case, but I want to see the instructions in writing, as that button is used to pair devices as well as to clear the device paring list.

Also the so called Wyze Setup Guide https://support.wyze.com/hc/en-us/articles/4405875506587-Wyze-Buds-Setup-Guide is a joke!

I am not sure where Wyze keeps a copy of it off the top of my head, but I do know that most of the quick start guides are submitted to the FCC, so you can often grab a copy of that from the FCC or a 3rd party FCC tracker like the following:


Note, that this is as close to a “User Manual” as you will find. Other than the Quick Start Guide, things should be fairly straightforward with opening the device in the app and changing settings how you want.
