Microsoft Graph API notification on invite to a folder/file is not working

Question

Hello, I am currently using this api https://graph.microsoft.com/v1.0/sites/${sharepoint_id}/drive/items/${file_id}/invite that invites a recipient to read/edit a document it's working but it's not notifying or sending an email to the recipient even the sendInvitation is set to true.

Here is my payload:

{
  "recipients": [
    {
      "email": "sample@mail.com"
    }
  ],
  "message": "Sample Message",
  "requireSignIn": true,
  "sendInvitation": true,
  "roles": ["read"]
}

Hello Joshua,

Thank you for reaching out to Microsoft Support!

Many people have recently experienced issues similar to yours, using application permissions with corresponding success but not sending mail, and have no problem with delegated permissions, so the issue may have occurred when the API side changed.

It is recommended that you use delegated permissions or open a support ticket instead.
