@gmlewis upon further testing, I've actually found that this webhook delivers an map of permissions in the API. This isn't very well documented IMO but could be inferred I guess. I've updated the event type to fix this. Here's an excerpt from a webhook event I received from GitHub during integration testing:

{
"action": "created",
"personal_access_token_request": {
"id": 11233,
"owner": { /* ... */ },
"repository_selection": "all",
"repository_count": null,
"repositories": null,
"permissions_added": {
"organization": {
"organization_announcement_banners": "write",
"organization_events": "read"
},
"repository": {

"metadata": "read",
"security_events": "write"
}
},
"permissions_upgraded": {},
"permissions_result": {
"organization": {
"organization_announcement_banners": "write",
"organization_events": "read"
},
"repository": {

},
"created_at": "2023-07-07T00:37:57+09:00",
