Webhook not sent when changing org member role

I’m working with the GitHub hooks since a while now, and I have noticed that there is no hook sent when changing the role of an organization member.
I don’t know if this is a known issue or am i doing something wrong?

Currently, GitHub didn’t provide an organization event when changing organization member role.

The organization event has these action types: deleted , renamed , member_added , member_removed , or member_invited .
