Multiplay Hosting Linux Permissions Issue (UNREAL ENGINE)

Hello,

I am using Unity Multiplay to host my Unreal Engine game.

Currently, I am having trouble write permissions in my directory. I am unfamiliar with Linux and how to enable these permissions for the Server Machine, so any advice is appreciated.

Below, you can find a screenshot of my logs. I am receiving the errno=13(Permission denied) error in multiple places. My assumption is that I need to enable write permissions for my project, but I am unaware of how to do that.

I understand I need to grant permissions via Bash/terminal commands. However, how would I execute these commands for the hosting machine?
