[Scheduled Tasks] needs security options
The "security options" section of the General tab in the Task Scheduler MMC snap-in doesn't appear to have an equivalent in Windows Admin Center. This prevents configuring options such as running the scheduled task even if the user is not logged in.

On top of this, it defaults to only running if I am logged in, which is perplexing considering that this is supposed to be a remote management tool.
