Getting data from sharepoint permissions problem

I am trying to get a list of sites, or a list of drives on a given sharepoint site. the app that is registered has the below permissions. I have confirmed that I am using the associated clientid,secret,appid to get my token.

When i make my call:

$myUrl = "https://graph.microsoft.com/v1.0/drives/someDriveId/items/root/children";

I get:

    [error] => stdClass Object
    (
        [code] => accessDenied
        [message] => Access denied
        [innerError] => stdCl开发者_高级运维ass Object

What am i missing?

Hi @bart2puck Can you please decode your token and check if the above permissions are available in it here https://jwt.io/

if you are trying to list the children of the drive, these are the permissions required for it:
