Emoji don't show in LINE messenger

Sorry for my poor English.
I’ve installed LINE messenger using Bottles.
Everything works fine, except the emoji cannot be displayed in the dialog.
It’s shows a blank font.
Do I need to install some dependencies in Bottles setting?
Or is there any other way to make the emoji display properly?

My Linux system is EndeavourOS with KDE Plasma desktop.
Bottles is Faltpak version.
