Failing to disable HiDPI scaling for telegram

hi. my telegram text and icons are pixelated after changing global scale to 125% in kde plasma. I’ve been trying to use this solution but it doesn’t work. I copied /usr/share/applications/org.telegram.desktop.desktop to $HOME/.local/share/applications/telegramdesktop-no-scaling.desktop and edited Exec to Exec=env -u QT_SCREEN_SCALE_FACTORS telegram-desktop -- %u after that i run this command update-desktop-database ~/.local/share/applications and now I have two telegram in my application launcher. when I choose the user specific one I got this error:Invalid object path: /telegramdesktop-no-scaling .
