Hi Satyam Rinayat,
Thanks for reaching out!
As per the documentation, me/followedSites
supports only the delegated permissions.
I tried from my end by consenting to "Sites.Read.All
" in Graph Explorer. It works fine.
Forbidden error occurs when access is denied to the requested resource. The user might not have enough permission or might not have a required license.
Could you please verify by consenting to "Sites.Read.All
" and execute the endpoint in Graph Explorer?
Hope this helps.
