How to run a guest process as administrator?

I am trying to fix a Windows 10 instance issue and I put a powershell script on the VM, tested it on the VM and it was working, the script need to be run as administrator.

Now I want to use a workflow to run this script, I create a guest operation-> run process, it did run the script but it's not runing it as administrator, so it failed.

Is there a way to run a process in guest VM as administrator?

Thanks!
