MacOS LaunchDaemon - Zshell script won't expand ~ tilde

Question

So if I place my plist file into my /Library/LaunchDaemons folder my zshell script won't expand the ~ to the current user logged in. I have to specify the full path on my shell script to the user where I want a file to be placed. ie Users/myusername/filepath/mylog.log

However, if I put the same plist file into the /Library/LaunchAgents folder and refer to the same file, the ~ in the .zsh script expands just fine. I'm confused by this behavior? (I can just put ~/filepath/mylog.log and it expands no problems

(The zshell script I'm launching is my /usr/local/bin folder.) I use the ~ extensively in my scripts so I'm trying to figure out how to get my zshell script to expand the ~ when I have a plist executing the file from the LaunchDaemon. (I need the script to launch in sleep mode or when the user is logged out.)

So unlike Agents, Daemon's require that you put the user and group that you want to run the daemon under. Since ~ is an environmental variable equivalent to $HOME (same thing) the .plist / Daemon doesn't understand where $HOME is if you haven't specified which user account. Make sense. Do that this way:

<key>GroupName</key>
<string>yourgroup</key>
<key>UserName</key>
<string>myusername</string> 

Please note - Launch Control app can be very helpful for this.
