Need URL update under Microsoft Graph Permissions in the 'apps.dev.microsoft.com' portal

When I click on any of the URLs for a further explanation about the differences between delegated and application permissions, I'm redirected to an article that does not explain the differences: https://docs.microsoft.com/en-us/azure/active-directory/develop/active-directory-protocols-oauth-code 

Here's is the updated URL that it needs to direct to:
