The spacing between each privacy icon.
*icon-size*: ++
typeof: integer ++
default: 20 ++
The size of each privacy icon.
*transition-duration*: ++
typeof: integer ++
default: 250 ++
Option to disable tooltip on hover.
*modules* ++
typeof: array of objects ++
default: [{"type": "screenshare"}, {"type": "audio-in"}] ++
Which privacy modules to monitor. See *MODULES CONFIGURATION* for++
more information.
# MODULES CONFIGURATION
*type*: ++
typeof: string ++
values: "screenshare", "audio-in", "audio-out" ++
Specifies which module to use and configure.
*tooltip*: ++
typeof: bool ++
default: true ++
Option to disable tooltip on hover.
*tooltip-icon-size*: ++
typeof: integer ++
default: 24 ++
The size of each icon in the tooltip.
