Can I reset the lab

I'm new to ES as well as Linux. I just started the [Elastic Observability Engineer] courses. (Loading)

On Lab 1.2: Heartbeat and Uptime, I somehow covered a executable file which stop me from going further. Then I deleted it and not able to get it back since I don't have permission
So I'm stuck on Lab 1.2
The executable file that was deleted is called "heartbeat" under home/elastic/heartbeat
Is there anyway to get the file back or reset the lab?

Thanks

I sent you a private message about replacing your lab.

Best,
Andre
