How to change badge color or other properties?

[cyril36]

Is your feature request related to a problem? Please describe.
By default the tabs badge color is red.
I would like to be able to update the properties of the badge such as the color.

<TabScreen
          label="Scheduled"
          icon="clock"
          badge="mybadge"
         badgeProps={mybadgeProps} //possible solution
        >

Can you help me to find a solution to update it?
