I can't change the height because of a big icon

[bigrand]

This is what it looks like:

Config:

trayer \
    --edge top \
    --align right \
    --height 20 \
    --expand false  \
    --transparent true \
    --alpha 0 \
    --width 20  \
    --monitor primary \
    --widthtype request

I'm on Wayland using Xwayland
