BlackEye | A ProJect aim to creat a BlackEye | Android library

I've got kali linux from microsoft store.

I wanted to run ./ngrok authtoken

but got -bash: ./ngrok: cannot execute binary file: Exec format error

so I tried chmod +x ./ngrok authtoken and sudo chmod +x ./ngrok authtoken

but either way I get chmod: cannot access 'authtoken': No such file or directory chmod: cannot access ''

what should I do? I really need to run ./ngrok authtoken

P.S: I want to use blackeye and when I chose the number it downloaded Ngrok

edit 1: I downloaded another version from https://ngrok.com/download and I removed the previous Ngrok in blackeye directory and unziped the new one instead. now I'm getting bash: ./ngrok: Permission denied

edit 2: It's been 12 days with no accurate answer guess I gotta get the real Kali Linux and the problem is the windows version.

This is my svg, the eyes blink every 12 seconds, but I want the user to be able to trigger that on any mouseover event. So restart the animation on hover.

I've tried adding begin="mouseover;...." to my svg animate tags, but it just triggers that lone animation, not all 6 animations, and I don't want it to trigger when the user hovers over a small shape, but rather over the whole svg.

I'm not keen on javascript because it slows the load time. I'd love some assistance, it'll help those impatient to view the animation again.
