Shortcut to make a note pop up on my phone and watch at a specific time?

I am a teacher, and I need to view a few passwords to log into teaching stations. I do not want to have to take my phone out to do this or interact with my AppleWatch. Is there a way that at a specific time I can have a Note pop up on my phone and on my watch with a specific note that will display the passwords so I can just raise the watch up and view the passwords without needing to interact with either device? I tried a shortcut to have a note pop up when I arrived at the address of the school, though it has never worked. It seemed to add the passwords as reminders but they never display on my watch or phone.

Thanks for any help with this!
