Button Color Change Issue

[Sandeep khatri]

Hi,

I've created a "Join Meeting" button that functions correctly, but I'm unable to change its color.

Here’s the current implementation:

<Row>
<Name />
<Widget>
<WidgetId>${JOIN_MEETING}</WidgetId>
<Name>Join Meeting</Name>
<Type>Button</Type>
<Options>size=2</Options>
</Widget>
</Row>

Could you please guide me on how to modify the button color? I tried many things but no css is working here.
