If I understand your questions correctly you want to act on a button press (or multiple on waking).
If you can provide a step by step example of what you are looking for I can indeed help
Here are some pieces anyways.
The first Snippet is how to read and write a counter to your SPI memory, this will survive any powerloss/reboot you have.
The second goes in your startup / main code that detects the reason for booting, Upon botting read the SPI, then sleep for about a second or so, As your pressing the button you can inc the SPI index value to +1 then after your sleep cycle on boot act on it or another method.
I personally use the following method below to have the chip detect that its in a crashing loop then to kick off a debug safe mode to report in if that were to ever happen so I have a chance for recover with FOTA.
I hope this points you in the correct direction, if not Ill be back this week and will watch for your reply.
