How do I get an info about battery percentage that powering up the Arduino

[SmartIscar]

I found a solution in this forum. there is the link:

XIAO BLE Sense battery level and charging status

Thanks Dave for checking it out. I assumed external circuit with voltage divider would work but did not want to have external circuit due to small form factor of my POC and also as XIAO already has a charging chip in it, this feature should have been out of the box Hope Seeed will fix this or document it so that someone can read battery without external circuit.
