How to transfer files into HTB pwnbox?

Hi all, a really noob question here. I am in the midst of HTB academy’s hashcat module and encountered a question where i needed to check the hash of a .7z file to be downloaded on my own host machine. After downloading i cant seem to transfer it into pwnbox. I tried drag/drop and copy/paste but neither seems to work.
I did a quick search on google regarding this but i dont seem to get any hits.

Hey! You are not the first to ask that so dont worry. Copy and paste the download url into the pwnbox and download it there. It doesnt require any authentication to download.


thank you. it works
