Space permissions update webhook no longer works

We were using the webhook for updating space permissions and with the new changes I see that is not valid anymore.

Does this have to do with the new styling and functionality of Space permissions?

Webhook → space_permissions_updated

Before it was triggered when we would add/update a user/group and hitting the “SAVE” button that it was at the bottom of the page.

Now I am adding a new user group, hitting Save and nothing happens.

Any thoughts about this?
