It's not a forking process so it'll run in the foreground.
You can use a service file or something to mount it.
I have some examples for Dropbox and Google Drive. I'm guessing by the names you are using OneDrive so there are other tweaks for OneDrive that other folks recommend. A forum search would yield that info.
