Using AzureR family packages in R to access azure resources

I would like to use the AzureR packages to access resources on Azure.
For example the ‚Microsoft365R‘ to access SharePoint!
site <- sharepoint_site("https://myaadtenant.sharepoint.com/sites/my-site-name")

I'm getting a browser popup for authentication. I am the owner of the sharepoint site I'm trying to access to, but still I need more previlage on Azure side which I don't know what are those ?!

Here is the error message I'm getting after putting my credentials :

Need admin approval needs permission to access resources in your organization that only an admin can grant. Please ask an admin to grant permission to this app before you can use it.
