I w̲a̲n̲t̲ a denial of webcam access

For years, I have frequently needed to dismiss an annoying popup that says

Attention required

Denied webcam access to Lenovo.Modern.Im.PluginHost

I have specified that I don’t ever want this module to have access to the webcam.  I am very tired of this popup.  Is there some way of blocking it?  My attention is not required.
