Split chrome icon in latte dock

Hello, everyone.
I have installed some chrome app in my manjaro (kde). When I open them it opened and show chrome icon in latte dock (I opened 3 app but only one icon). How can I split them to serveral icon (and use its app icon) ?

Thanks for your help.

Right click the icon and look for a setting related to grouping (group / ungroup). There might also be an option to grouping in the settings of latte dock, thats how it is with the icon-only taskmanager.
