Rofi icons not showing when launched via sxhkd shortcut

I’m running into an issue with Rofi using a pre-configured setup from adi1090x/rofi. When I run my launcher script directly in Alacritty, the icons show up fine, but when I trigger it using an sxhkd shortcut, the icons do not appear.

Here’s my sxhkd shortcut:

super + [u/space](/u/space)
    /home/albert/.config/rofi/launchers/type-2/launcher.sh

Running the script manually works:

/home/albert/.config/rofi/launchers/type-2/launcher.sh

I thought it might be related to environment variables. Here are the differences I noticed

Environment variables when running in terminal:

• TERM=alacritty
• WINDOWID=31457283
• ALACRITTY_WINDOW_ID=31457283

Environment variables when running from sxhkd:

• TERM=linux
• WINDOWID is not set
• No Alacritty-related variables

Other than that, most variables seem similar, and they don't seem to be odd to me. ¯\_(ツ)_/¯

Any ideas on how to fix it so that icons show correctly when launched from sxhkd?

Thanks.
