Normally PowerShell Core, when installed on a Linux box, will be accessible for everyone, provided the permissions are set correctly.
For the PowerCLI Core modules you will have to install them in a module folder that is accessible to everyone, instead of in the ~/.local/share/powershell/Modules directory as the documentation says.
There are, just in PowerShell 5.*, as number of folders where you can install modules.
Check the values in the $env:PSModulePath environment variable.
One of the directories in there is /usr/local/share/powershell/Modules.
Unzip the files in that directory, and the PowerCLI Core modules should be available to all accounts on the box.
