Improve migration error messages clarity
This error message is not helpful - "There was an error while loading the items. Please contact ShareGate support." . This one is also not helpful, since the Svc account we're connecting with has Site Collection Admin permissions, and was verified in Sharegate, when using the 'Check Permissions' feature - "When using the insane mode to Microsoft 365, it is necessary to have 'Site Collection Administrator' permissions at your destination."
