Enhancement: Add application permission check to purview retentionlabel and purview retentioneventtype commands #4450

Enhancement:

When executing the purview retentionlabel and purview retentioneventtype get commands, we will get a notification that we do not have the necessary permissions when using application-only permissions.

We should add the following lines in the commandAction of every command and update the tests. We also should add a remark to the docs.

if (accessToken.isAppOnlyAccessToken(auth.service.accessTokens[this.resource].accessToken)) {
      this.handleError('This command does not support application permissions.');
}

Original issue:

Description

Currently, when we execute for example purview retentionlabel list while using application permissions, we will get the following error:

After doing some research, I noticed that this was due to me using the application permissions. After logging in using devicecode and a custom app registration with the permission RecordsManagement.ReadWrite.All, it started working

I think that we should add a piece of code that checks if we are using appOnlyAuth and throw an error if this is the case

The error occurs on the following commands

• purview retentionlabel add
• purview retentionlabel get
• purview retentionlabel list
• purview retentionlabel remove
• purview retentionlabel set
• purview retentioneventtype get

Steps to reproduce

1. Login using --authType secret and a custom application registration
2. Execute command m365 purview retentionlabel list

Expected results

List of retention labels
