Dark mode in local Web client plugin?

Hi,

We have a plugin running in our product, but on the plugin seed 0.98. We are using it with recent versions of Clarity (1.2.0) / Angular (7.2.12) 

We would like to be able to change the theme in the plugin to dark mode when it is changed in the H5 client. Can you let us know if this is possible please? And if so, what would be required to do it?
