Why is there no beauty function for the POCO F7 Ultra video calls?

If you can't find the beauty function during a video call, please find the translucent white bar on the side of the screen after starting the video call, swipe inward to call out the Call toolbox, and you will find the beauty switch. 
If you can't find the white bar, search for [Sidebar] in [Settings], make sure the [Call toolbox] is turned on, and then start the video call to see if you can find the white bar. We apologize for the inconvenience, and thank you very much for your understanding and support.
