collapsibleTreeSummary: Change Color of clicked node?

[miklosmorada]

Hi @AdeelK93. First of all, thank you for this package! This made my life much much easier. Apologies for asking this question that seems pretty basic, but is it possible to change the color of the node that is currently clicked?

Example. If the node Mail below is clicked, can it be changed to a different color (e.g. neon green).

Thank you!

Best,
Miklos
