Installed from KDE "Get new icons" or the install script, no difference.
Telegram installed from Flatpak
By the way, this is the first time I have a missing icon. Used this theme (and Telegram too) in every single distro I ever distro-hopped to. Also, the Tela Icon Pack (2nd pick for me when Fluent doesn't look as good as usual with the distro) also from Vince, doesn't have this issue.
