MS Team App to fetch SharePoint list item

Question

I'm following the below link to create a personal tab in a Team App.

https://learn.microsoft.com/en-us/microsoftteams/platform/build-your-first-app/build-personal-tab

I need to fetch and display contents from a SharePoint list here. I get the below error-

{"odata.error":{"code":"-2147024891, System.UnauthorizedAccessException","message":{"lang":"en-US","value":"Access denied. You do not have permission to perform this action or access this resource."}}}

The user is a SharePoint Administrator and Site collection Admin.

Code-

var spUrl="https://****.sharepoint.com/sites/Project4thCOM2"; //hard coded SP Site URL  
var web = Web(spUrl);   

await web.lists.getByTitle("Teams List").items().then((items)=>{  
  items.forEach(element=>{  
      this.setState({  
        Title:element['Title'],  
        SingleLine:element['SingleLine']  
        })  
  })  
}).catch(err=>console.log(err))  

Could anyone please suggest how we can access the SharePoint list data here.
Regards,
Kevin

You need to get the access token to request the API.

Or you may try to use Graph API.
