Notification/Toast/Flyout/Popup to show current/present volume level when volume-adjust hotkeys (e.g. media keys) being pressed (for individual apps)?

Otherwise, I can hardly tell if it is the highest volume level right now, and determine if I have to seek to other boost solutions such as adjust per tab volume through browser extension, or adjust the master volume of speaker/device.
Or is that a bug, or do I have to enable some settings? the version is 2.3.0.18 on windows 10 22H2.

(I prefer and rely on EarTrumpet because all of the browser extensions I tried dosen't support media keys at present. Even if I can write one and maintain it for all platforms, firefox, chrome... other apps is also a big problem. I think EarTrumpet is the only right place to solve this. (If windows doesn't have the will to improve UX for per app volume adjustment.))

Similar disscussion: Feature request: play a sound when adjusting individual app volume levels But I'd suggest a visual one which conforms to the default windows/apps behaviour.
