:::caution Debugging tip
|
|
|
|
Browser camera APIs restrict this widget to only work in either `localhost` or `https`.
|
|
|
|
So if you're testing it out, be sure to either use `localhost` or `https`.

## General
|
|
### Tooltip
|
|
|
|
A Tooltip is often used to specify extra information about something when the user hovers the
|
|
mouse pointer over the widget.
|
|
|
|
Under the <b>General</b> accordion, you can set the value in the string format.
|
|
Now hovering over the widget will display the string as the tooltip.
