How do I find the path to the msi file windows launches when uninstalling an application?

I have an app installed on my PC. I don’t know where the original msi file is, or even if it exists. But, if I go into Settings -> Apps -> Installed Apps and uninstall the program, windows launches some msi, I’m assuming either a copy it saved or it knows where the original is.

I can see the task running in task manager. How can I find this msi file on my system?

For full context: my goal is to briefly uninstall this app, but have a copy of the msi, so I can reinstall it later.
