Describe the bug / error

There is an error on the documentation page Support for Content Security Policy (CSP) in SharePoint Online.

In the section Can I update the trusted script sources list using script or code? contains an example of code using CSOM.

// cc is the CSOM ClientContext instance you've created for your tenant admin url
Tenant tenant = new Tenant(cc);

// Get trusted sources
var cspTrustedSources = tenant.GetContentSecurityPolicy();
cc.Load(cspTrustedSources);
cc.ExecuteQuery();

// Add trusted source
cspTrustedSources.Add("https://cdn.host.com/source/");
cc.ExecuteQuery();

// Remove trusted source
cspTrustedSources.Remove("https://cdn.host.com/source/");
cc.ExecuteQuery();

I tried to use it with the Microsoft.SharePointOnline.CSOM nuget package version 16.1.26914.12004 (release date is January 30). There is no method GetContentSecurityPolicy() inside Tenant.

There is no method GetContentSecurityPolicy() in CSOM documentation.

Steps to reproduce

1. Go to https://learn.microsoft.com/en-us/sharepoint/dev/spfx/content-securty-policy-trusted-script-sources#can-i-update-the-trusted-script-sources-list-using-script-or-code
2. Try to use CSOM code example.

Expected behavior

A working code example should be written in the documentation. Or a special version of CSOM should be specified in which this code will work.

@Breathtaker : I just tested with that version and it worked like a charm. I think somehow your code is still using an older version of CSOM

@jansenbe Thank you very much. You were right. For some reason, Visual Studio was using an old version of Microsoft.Online.SharePoint.Client.Tenant.dll. It's possible that the NuGet packages were not properly configured, as both PnP.Framework and Microsoft.SharePointOnline.CSOM were added simultaneously.

I hope Microsoft will start updating the CSOM documentation again. The lack of this method in the documentation has confused me the most.

@jansenbe thank you again. You save my day.
