You can complete the Office 365 guided setup using the express configuration option, which automates some configuration steps.
After you create the Azure app that is needed for the SharePoint Online app, the express configuration automatically creates a SharePoint Online service account for the Azure app, and then authorizes the Azure app with Azure.

Set DisableCustomAppAuthentication to False
On the tenant, run the following SharePoint Online PowerShell command to set DisableCustomAppAuthentication to false:
set-spotenant -DisableCustomAppAuthentication $false
Disable Multi-Factor Authentication for the Global Administrator Account
To use the express configuration option, if multi-factor authentication is enabled for the global administrator account, you must disable it.
For more information, see "Turn on Modern authentication for your organization" and "Turn off legacy per-user MFA" in Use Conditional Access Policies in the Microsoft documentation.
After you complete the guided setup, you will enable multi-factor authentication again.
