How do I disconnect someone's account as observer of my daughter's canvas account ?

unknown

I think someone made a mistake to connect my daughter's canvas account as observer.
If my daughter changes the password, is it disconnecting? 
How am I able to know who are connected to my daughter's account as observer? 
I would like to delete any observers except me and my husband(her dad). 
My email is jyj798@gmail.com. 
I am looking forward to get answers from you. 
Thank you so much.

Hi @Yunjeong 

You'll need to contact someone at your daughter's school.  This is a public global forum for users of Canvas and has no connection to your local school.  

Also, I would delete your post or at least remove your email address, as you may get spam.
