Pressing my S-Pen button doesn't show charging?

[SVOHIO]

I bought a new S9 FE tablet with an S pen because I needed an S Pen to do what I need to do for work and stuff. The pen is working fine as far as I can tell but when I try the methods of checking the charge or the pairing I don't get anything using the methods. The methods are described in the article link below. 

Method 1 - press the pen button while connected to the back of the tablet doesn't display anything

Method 2 - when I click the pen air command floating icon on the right of the tablet screen there's no settings for me to use to see the charge percentage. Nor do I see anything when I click the pen button.

@SVOHIO This is because the Tab S9 FE does not provide, nor support, bluetooth S Pen actions. Air actions is not available on the Tab S9 FE. Therefore there is no battery to check in the S Pen.

Hmm! I'm sure you know what you are talking about, but are you sure because I have all those settings available within Settings for the S-Pen specifically. And when I went through the tutorials for the S pen1. I was able to do everything in the tutorials and working with Air Commands etc.

Digging, i found some clarification.

The S Pen, which comes with Tab S9 FE, has no Bluetooth functionality. The Tab S9 FE itself should provide Air actions when used with an S Pen Pro. Not clear if it would work with other Bluetooth S Pens and not clear if you could charge any of them on the back of the Tab S9 FE.

GOT IT ! Thanks for taking the time !

Oh, one more thing. What would the button on a non-bluetooth S pen be- used for?

@SVOHIO Click the button to erase. Click the button to open the Air command menu. etc.
