How to update the Site Title and description of modern team site?

Question

Is there any way to update the SharePoint Online Modern team site "Title" using Rest API or graph API.

I tried the below code, but it is not updating.

 import { Web } from "sp-pnp-js";

let web = new Web("https://company.sharepoint.com/sites/sitename");

web.update({
    Title: "New Title",   
    Description: "My new description"
}).then(w => {

    console.log(w);
});

I figured out that Microsoft is using https://company.sharepoint.com/sites/sitename/_api/SP.Directory.DirectorySession/Group('GroupID') this api to get the properties and update the properties. But I cannot use this as it is not documented.

Is there any API which will update the title and description at group level?

By default, a SharePoint modern site is automatically connected to a Office 365 Group. We can use Azure Active Directory Graph API to update group properties, then it will sync to the modern site.

PATCH https://graph.microsoft.com/v1.0/groups/{id}
Content-type: application/json
Content-length: 211

{
  "description": "description-value",
  "displayName": "displayName-value",
  "groupTypes": [
    "Unified"
  ]  
}
