I am setting up a graph api in order to access oneDrive and read/write files. I am trying to setup all this for our customer organisation, they added me as a guest user. When I want to access their oneDrive, I get authorization error(accessDenied). I am wondering do they need to give me specific permission? In app registration we set this option Accounts in this organizational directory only (XXXX only - Single tenant) shall we change it to Accounts in any organizational directory (Any Azure AD directory - Multitenant)
