How to highlight a feature on mouseover/hover in JS API 4.15?

[ChristianBischof]

I'd like to highlight a feature whenever the pointer is hovering over it, (by changing the features color). Currently the features are grey filled out areas and they should become red whenever a feature is hovored.

Thanks in advance for your help
