Volume Control on Kospet Prime

Sometimes on a video call or on watching a video clip, I would like to be able to turn UP or DOWN the audio volume. Is there a convenient way to do it without quitting the video and calling up a volume control app? I have seen Mr Smartwatch Ticks using a side slider to control the screen brightness. Is there a similar slider for controlling the volume?

Yes. Its called Volume Control by the same developer. Check Mr. Ticks videos to the link to his cloud page.
