I have yabai in login items twice

[Tobias]

One is located at /opt/homebrew/Cellar/yabai/6.0.9/bin
The other at /opt/homebrew/bin

is this supposed to be like this?

[Bellavene]

One is located at /opt/homebrew/Cellar/yabai/6.0.9/bin
The other at /opt/homebrew/bin

/opt/hombrew/bin has only links to the executables.
/opt/homebrew/Cellar/yabai/6.0.9/bin is the real location

By the screenshot, no. it is not supposed to be like this.
Look into ~/Library/LaunchAgents/
Is there one com.koekeishiya.yabai.plist file?
