Status menu: Menu argument not being passed

I'm doing a status menu item that I'm going to use to open Rider with env. vars loaded (Rider has a problem with loading env. vars when starting it normal).

It should be simple, but I must be missing some obvious here.

This is my assumption after reading the docs:

Scripts are read and executed as is (just like a normal script)
To create a menu with clickable menu options you create a if/else where you echo your menu in if (depending on the if-statement)
When clicking a menu option the script "re-runs" but with an argument set that corresponds to the output of the menu option.
You then "catch" this argument and do whatever you want.

But the argument seem to be empty for me. I tried a bunch of stuff (just one example posted here)

My simple menu:

Platypus app

Platypus version

Found this issue, but it didn't help me much:

Status Menu variable not being sent to bash script #226

The script:

#!/bin/zsh

openRider="Öppna Rider"
quit="Avsluta"

if [ $# -eq 0 ]
then

    echo $openRider
    echo $quit

else # else for now when testing

    #Open Finder if it works, just for testing
    open -R .

    # TODO Load external env vars.

        #open ~/Library/Application\ Support/JetBrains/Toolbox/apps/Rider/ch-0/232.9921.83/Rider.app
fi

Bonus question

How do a get an alert? echo alert from documentation is not working for me (becomes a menu option with the "error text" if there is something wrong).
